Technicaly none of the shops have a "Fixture" not "jig" , Sorry thats the Jig and Fixture class inside me talking. I think it would be a little iffy trying to fit that exhaust on, but if it workds you'd be abit of a pioneer. Do you have a welder at your disposal?
it has been noted that some 5sfe manifolds "could fit" but you do need to mod it to. i have no idea what needs to be done. and i don;t think i will be trying to do it anytime soon. but yeah if you end up getting bored one day and want to try it, make sure you take notes. hahaha!
the rear section should fit right up but the front would need to be modified. the GE motors will require serious mods to get the 18X system to fit up front.
*Thread hijack..... I like those rims because they are different.... You need a crazy body kit though to make them really work....
