i'm restoring a 1968 mustang, raven black with red interior. Are there any weak spots that i should look for on this car, frame rails, or anything else? should i modify the front brakes to disc? or is the drums safe enough? the car currently has the 200 I6 in it and i was wondering if the motor still ran if it was worth keeping? or if it doesn't run should i put a 3.8 liter v6 in it? i currently have a 302 but it needs extensive repairs before it can be used and i was wondering about this. Any idea how much a new hood, trunk and driver side door will cost? i'm lost there since this is my first serious attempt at fixing it up.. any help is appreciated!
