Yep, it was me who bought the old PF mag one, which had potential, but needed alot of work, and should of been done to a rust free car in the first place, I had the shell on here for 3 months for £100 then scrapped it, minus all the rwd kit.I can be done, but you gotta know alot about Mk2's as that's what running gear it would take, bear in mind you need to change the rack, fuel tank position, engine mounts, fabricate a tunnel,turret and link the rear, to name a few of the bits, if you need to know more I can tell you how to do it, but, I placed my shell ontop of 2wd cossie running gear and it looked alot easier to do, and cheaper.
and this is it with 2wd cossie running gear under it, it all fits in the right place and adjustable TCA's/comp strutts would bring the front track inline
here's the rear with cossie independant axle, better handling than an Atlas axle, but not better traction imo.
and here's under the engine bay, with a bit of cutting the cossie crossmember would fit and you could even run power steering
try an ad on rallyusedparts.com as there's often ex rally shells allready converted on there, or
do as I did, scrap that idea and buy one of these with all the hard work allready done!
Any probs contact me and I'll help where I can.
