Damaged trans?

I have to get it back to the garage again this weekend. I just found 2 904s for $50 a piece. I figured it wouldn't hurt to have a few extras laying around. I've been doing some reading though I found out the moroso u joint girdles I had on are junk unless you have a 4 link to control the pinion angle. Now that the yolk is drilled can I get long u joint straps to go the whole way through? Part #? I seen some on mancinis website but said it required a certain yolk. Do I need a new yolk now too? Its a 742 chunk.
