I use the 5115 on my Miradas.
Pretty much, they drop right in.
A small ding by the rag joint might be required.
This varies due to the condition of the stock rubber K Frame mounts. If they are compressed, the header might rub the joint.
The 90° oil filter adapter has to be removed.
I used a Fram PH8 oil filter, screwed directly on the blocks flat oil filter plate.
Choose flange bolts designed for use with a smaller size wrench, as the tubes are very close to the bolts.

it says that they are 4 the larger body cars like cordobas. im concerned because they dont have the drop down 2 tubes that the steering goes through like my current ones.

I use the 5115 headers on my LeBaron and had to "massage" the area where it passes by the steering knuckle just a little bit. I ground down the steering knuckle a little and they fit fine and I use solid mounts on the body and engine. +1 on Mirada's post-the biggest pain in the neck are the flange bolts. I have to screw in the front one then the back one and start all of them before I tighten any down. They are much cheaper than a custom 4-2-1, but I lost some HP switching to them.

I had to remove part of the bulge on the passenger side were number 6 cylinder tube goes by. The bulge is for the A arm adjustment. I had no problem with manual steering. I also have solid K member attachments and used Schumacher S6 to 360 adapters. The pic of the green engine bay is from another swap, you only need to remove the bulge as the rounded upper part was to get to number 6 plug through the wheel well (RB eng).

nice! thanks for the pics! i hope these headers don't overlap my exhaust ports like the 1.625" ones do now. now to find a nice slightly bigger than stock gasket. im thinking a copper or aluminum one? can trim if need be.

Back in the day, I found that the Percys aluminum gasket wouldn't work with the 5115.
Best to lay a gasket over the header flange for a visual, before you have the headers in the engine bay.

Yes they work u have to message the tube at the rag joint. But they do work u dont have to take the steering linkage loose or anything. I uused to bust those a-body style headers on man hole covers cause the driver side hangs low but not with 5115 and they wake up that motor
