My 77 ford that has a 351M with an automatic (C6 I think). Ive aquired a 76 with a 460 and a 4speed granny.. They are both 4x4's.. I'm wanting to kinda rob the 76 of better parts, exchange motors and resale the 76.. My question(s) are basicaly how huge of deal "should" this be? Any chance that the will match up to the new tranny or am I dreaming.. Thanks in advance, you guys are always very helpful..
