Here's some food for thought. If you really want to use the Tahoe frame, cut the rivets/welds from the crossmembers and steering linkage, cut them to length to make them shorter, then weld/rivet/bolt them back together. It's too long too, then you'll have to shorten the frame.
I'm in the same delima, my '41 is going to get another frame under it. I just haven't made up my mind what to do.
Good luck
