Jaguar XJ6 IFS - A-body swap...

Here are your track widths. Listed for both the +73 cars and the '72 down cars. That's NOT a mounting face to mounting face measurement, but rather the track width which also involves the backspacing of the rims. It should be fairly close, you can see the rear track is different from the 57 1/8" drum face to drum face that's listed for the A-body 8 3/4's.



Seems like a lot of work to end up with '70's technology, but that's how I feel about the coilover conversions too (they're a Mustang II design!). Realistically it's generous to call either of those designs '70's tech too, they go back further than that.

But from a fabrication standpoint I think it's awesome just to see it done. If executed properly the result shouldn't handle any worse at least, and it opens some doors as far as some of the additional components go too. And really the biggest advantage is the same as the coilover conversions, rack and pinion steering and more room for headers. But it should be a lot cheaper than that if you can do the work yourself.
