Not that I know of and I wouldn't do it, the reason being is that European parts are VERY expensive if something goes haywire. Depending on your budget I would go with a top name reputable chassis builders IFS or their Mustang II kit. Be VERY carefull with this because there are some really bad cheaply made parts out there that have caused accidents.

My son has a 36 olds and the front of the frame bumps out for the coil spring pockets You can do a complete Jag brake rebuild cheaper that buying a sub frame kit. I would trim the olds frame bump outs then weld in 1/4 flat plate. then install the Jag I haven't been out with a tape to do a lot of measurements but it looks like an easier job than a front sub frame kit or swap. we have 4 jag suspensions in the shop for our projects. We buy fronts or rears for $ 100 to $ 125 we pull. .There are a lot of posts on the HAMB forums about Jag swaps. do a search for jaguar suspension swaps.
