the car looks to be in pretty good shape from there. so thats a start.... my buddy said that he had to get different motor mounts.. tranny mounts.. a different driveshaft ( junkyard parts car should have one easy... ) rear end... ( same parts car.. they are normally left on those cars ). this disc brake setup off of a Junkyard Granada ( youll need the outer tie rods for that as well but the spindles bolt on to the existing Mustang stuff-- stock wheels wont clear the hubs on the Granada stuff though.. might be able to pick the Grananda rims too.. all in all that can be done for under $500 if you can find a decent parts car ). some of the steering parts had to be changed.. i think it was the centerlink parts.. once again.. find a decent parts car and that will all be on it. other than the obvious engine and tranny i dont think there was anything else. the gauges i think are the same for the V8 and 6s.. they all have floor shifters but i think V8s had different ones for their trannys. coil springs are different... control arms too i think. basically its gonna be a whole rebuilt front end. not that big a deal as it seems. so basically

- rebuild the front end with V8 spec parts ( about $500 for the kit i think )
- Granada disc brake upgrade ( $200 - $500 for the parts.. rotors and calipers are Pep Boys parts need be.. dirt cheap there )
- steering centerlink ( not sure on price.. they are reproduced though )
- Rear end ( about $150 at the local pick a part.. complete )

its not really that hard to do.. about the same as any domestic engine conversion but some people whine about it more when it comes to the suspension parts.. but hell.... any other car really should be upgraded when doing the same as well. let me know if you need to know anything else... i need some coffee lol
