Completed trans mount

 By splitting this PS plate in the middle, I could gained access to grind a little and avoided having to hit the hole placements perfect:

Weld through primer;  Right when you start to weld you stub out, get a couple burn backs and giant spatter balls, then it settles down and welds fine for the rest of the bead.  That may be due to some other non ideal conditions here, but I suspect the primer as the cause.  That said, it's a relatively minor issue in exchange for rust protection on these inaccessible areas:

Threaded bosses sticking through the rail:

Cap for the end:

I didn't grind these welds down because 1: I didn't bevel the edge prior to welding and the penetration may not be that great, 2: nobody will see them (except all of you!).  Blue and in the corner:
