Ive got a 69 grande 302, with a 3 speed, my uncle just gave me a t-10 4 speed, is this going to be basically a direct swap, or am i going to need a new crossmember or anything like that? thanks
The crossmember should be the same as with the tranny mount. I think that the only thing you might have to change is your slip yoke. I think that some 3 speeds had a 25 spline and some had a 28 spline. The 4 speed is going to be a 28 spline, so you might need a new slip yoke.
