Working on transmission mount.

I cut out the original fixed transmission crossmember as it makes getting the engine in and out a royal pain. The problem with cutting it out is that there is nothing to bolt a replacement to. The crossmember is only boxed light sheet metal and is insufficient for bolting a heavier gauge center section to. My solution was to use 2 3/8ths outside square tubing, which slid into the stubs nice and snug. Finding that size tubing is a bit of a bother, but it works perfectly. I then used 1/2" bolts to fasten it within the frame rails. Capped off the ends with some 3/8ths plate and welded nuts inside for both the facing plate and the frame fasteners.

There will be a 2" wide (1/4" plate) strip bolted underneath, as part of the center section, with the rest of the center section bolted both below and to the sides. I planned it like this so that I wouldn't be hanging the mount from something that the bolts were in shear.

more pics when I get that done.
