Well first off--the M2 and Pintos were pretty short wheelbase cars so even if you did complete M2 front end set up on a longer car it wouldn;t be correct---

Having said that, ackermon isn't too big of an issue except in turns such as something that takes a lot of manuevering

Have you looked at complete frame front and rear from something like an Ford Expedition??? Explorer?? disc brakes, right weight package, wheel base maybe close enough angles work out and independant rear suspension??
