I'm mocking up my engine/trans in my A frame. 59a with 39 trans, F-1 crossmember, pedals, and master cylinder. I want to leave the stock crossmember in place as these little frames are pretty spaghetti-ish plus I want to bolt the F-1 crossmember in so I can drop it out if needed. The master cylinder is going to interfere for sure; the hookup for the torque tube to trans looks pretty tight. I posted this on the Barn and got one good answer, but that was he usually cut the stock X member out. Any other similar experiences? My thought right now is to cut down the stock X member, plate it for strength, then reconstruct some stock style flanges.
