never mind - found a manual at oldcarmanual.com and found the piece I was missing and went and dug through the stash and lo and behold there it was (whew!) its in the parts washer as I type and the project keeps crawling along....
ever work on a car and get in a jam where things don't come out like they should and you think to yourself "man, I'd like to meet the ##@!@$% who designed this and see him try to fix this..." ran into those same exact thoughts pulling the trans this morning and then I realized - hey, wait a minute, I AM the $%&^# who designed and built this frame this way 
note to self, make the next trans crossmember removable!
