    Frame rail repair

    My left front frame rail is rusted out, right behind the wheel, where the frame becomes straight. I have a solid parts car to rob a clean rail from. I have never done this before. Is it safe to just support the car and cut out the piece I need? Thanks

    Schumacher mounts /6 to 360

    I just dropped a 360 into my Diplomat using some Schumacher conversion mounts. I had to use two washers per side as spacers to take up the gap on the rear two ears of the mounts, which I understand is common practice when using these mounts. I can just barely get the mounts to sit square in...

    Solid K frame bushings

    I'd like to find a set of aluminum or polyurethane bushings to replace the old rubber K frame bushings in my Diplomat. It's getting a 360 where a slant six once was, and since it's 450lbs lighter at the moment, now is a good time to change the bushings. I would be very grateful if someone...

    Need help deciding transmission part number

    I am pretty sure I'm dealing with an A998, built in 1988 (for 1989) from the Kokomo plant. If anyone can verify that, I'd appreciate it. I bought the car from the original owner, an older gentleman, which leads me to believe it is original to the car. 1989 Fifth Avenue, 318 2bbl Part number...

    Just a few questions

    I am picking up a parts car for my '80 Diplomat coupe this week. It is an '89 5th Avenue. Here's the plan: Take the 7.25 rear out of the Diplomat, put in the 8.25 from the 5th Avenue. I do not know the ratio but I am suspecting it to be the 2.26 or 2.45. I have read that the 2.45 carrier will...

    Slant six to 318

    I've got a slant six in my 1980 Diplomat coupe and I am looking at buying a low mile (29,000) 318/904 combo to swap in it. A few concerns I have are as follows: It is my daily driver and cannot be down for much longer than a weekend. Is my current driveshaft going to work with this swap...

    FOUND Printed circuit board

    In need of the printed circuit board for water temp/voltage gauges. Oil light, brake light, washer fluid light are also contained on this board. Mine is fried behind the voltage gauge, and my attempts at soldering it have been in vain. Also; how does this board detach from the cluster of wires...

    Looking for bumpers without vertical rubbers

    I have a two door Diplomat and it needs a rear bumper. I would like to find one without the little vertical rubber things. Will post pictures to be clear. I have seen some M bodies with these bumpers. I am wondering if they are available as re-pops or if there's a good source for decent used...

    WANTED Diplomat interior door handle strap

    I'm in need of an interior door handle (strap) for a 1980 Diplomat coupe. My interior is tan but I'm not going to be too picky about the strap color if I can get ahold of one. The one that broke off was screwed on from the inside of the door panel. I'm guessing the rivets didn't hold up, or...

    Prepping Diplomat for road trip

    Hey all, I’m trying to prepare my Diplomat for a trip from Ohio to Georgia and back. 1200 miles each way. It made it there last time no problems, but this time it’s been through an Ohio winter, and I’m sure there are some things that need gone over to ensure it’s safe. I’m not too worried...

    SOLD 1980 Diplomat coupe

    I am looking to either sell or trade my 1980 Diplomat. It is a two door, slant six automatic. Dark brown exterior with flat black hood and lower doors. It is a reliable car and can be driven daily with no worries. I do drive it daily to and from work, about sixty miles total. I drove it from...

    Paint questions

    First off, I would like to say that I know nothing about body work. All I know is that my 1980 Diplomat coupe has no rust holes or dents, but it does need a paint job. Previous owner painted the hood and lower half of the car matte black, with the rest being original dark brown. It doesn't look...

    Fuel gauge troubles

    1980 Diplomat, slant six. I started having an issue with my fuel gauge a couple months ago. I would be driving and the needle would plummet down to E, past the empty mark as if the key was off. Sometimes it would come back up to the accurate level where it was before. It did this on and off for...

    Slant six distributor WORN OUT!

    Okay, so awhile ago I posted a thread on here about having trouble with my slant six ignition. Basically, my problem was intermittent spark. Usually the car would start up and run fine but as soon as I drove it around, parked and tried to fire it back up - nothing. I did find that I would get a...

    1980 Diplomat ignition trouble

    Here's the scenario: About a month ago I had new exhaust put on my Diplomat. The catalytic converters were done away with and the back of the head where the EGR tube goes in was sealed off. Ever since then, the car has been shutting down. This normally only happens when I am approaching a stop...

    Why am I even contemplating this?

    Right off the bat, most people will say this idea is stupid. I might even be one of those people, but hear me out. After owning three slant six cars, I've developed a strange love for the 225. Now, I know that I'll never make the power of a small block with a slant six (which is why I am...

    Question about center caps

    Here's my scenario: I have a set of the ten spoke aluminum wheels which came factory on some cars such as Diplomats, Miradas, etc. I am missing one chrome center cap. JUST ONE and it drives me crazy. I can't seem to find any for sale at a good price. I'm not even a huge fan of them anyway. Here...

    Road trip!

    I just got into a town south east of Atlanta, GA last night. My new job requires a week of safety training at their facility here, so from my home town in Ohio I took the Diplomat. I wasn't quite sure what to expect on the 750 mile journey, but the ol gal served me exceptionally well! Never had...

    I'm not very pleased with my oil right now

    Okay, so about a month ago I changed the oil in my slant six Diplomat. I was teaching my little brother how to check the oil, since he will be driving soon. He twists off the oil cap and the first thing I notice is moisture on the bottom of the cap (a color such as antifreeze and oil mixed) but...

    Not sure if this belongs here, but it seems to fit

    If anyone has any questions about Sure Grip rears versus "peg leg" rears, watch this. Simple, really. I love these old training videos, even if this one is from GM. Really gives us some insight into how and why they developed this kind of technology. This Is The Only Tutorial You'll Ever Need...

    Anyone ever used Yukon axles?

    I'm purchasing an 8 3/4 axle housing that came out of a '65 B body, and I'm going to use it for my 1980 Diplomat project. I have the sure grip unit, and I plan on using 3.55s. The best price I can find for axles is $160 each for Yukon from Randy's Ring and Pinion. Can anyone testify to the...

    Throw me some ideas! Low budget 360 build

    So.. I tore apart a 360 LA to get ready for a swap into my old Valiant, and that went by the wayside when the car was totalled. Now that I have the Diplomat, I'm finishing what I started. ANYWAY... What can I do to make this thing giddy-up-and-go? I have a mild 340 cam to put in, and other than...
