    After following several threads from Jeep forums regarding 8.25 rear axle with disc brakes setup that can work with old mopars, why not try the following to modernize these old cars and make them better. Well, I've actually come across another option that I like better. Something came up on my radar screen that REALLY got my attention. That is, the drop out IFS from a 93-04 Lexus SC300\400. It's a REAL nice looking piece and it's got a hair over 34" between the frame rails. Just like the F-body. It can use HUGE Turbo Supra front disc brakes and it bolts to the frame. F body front track width is listed as 60.0". SC300\400 is listed as 59.8"... Thinkin' out loud.... Haven't tried it but what are your thoughts?

    I saw someone else trying this too. I think it's a great idea if you can get all the bits to line up!

    If I was better at computers, I'd get a 3D scan of both K frames and check out the differences.
    The .2 track difference shouldn't be a issue

    Good job. How was the fitment with the JEEP axle? Could you provide some details as to the year used, etc... Thanks
