Rad is easy.just have one made like I did using a 4 core forklift center and custom tanks. Set the rad under the header between the grill and the rad support. strange that you had to cut the top of the rad header as I didn't need to with the 302 and the SBC's are shorter then the SBF's. I did have to cut the tranny tunnel opening back about 3" then move it up 2" to clear the AOD's bell housing. Driveshaft again an easy fix, just shorten the front and weld a chevy yoke into it, if it a 2 piece only the front needs to be shortened and rebalanced. Name maybe Mitsulet as I have the Fordubishi Tranny cross member again easy 3"x 1/2" flat bar lined up with the factory frame holes and a piece welded to line up the TH400's mount. There should be pic's of some of what I'm talking about in my build post. hope this helps it's looking good so far, keep it up.
