I was already planning on making my own body mount bushings, since the tubing i used in place of hat channels may not be the same thickness as original. But i'll probably reshape the tunnel alittle bit anyways just to be sure. I'd hate to get it painted and reassembled then find out the overdrive doesn't fit. And i have an ammo can i use as a center console so you can't see the tunnel at all, so it really doesn't matter if i had another hump in it.
