86 sm465 into 72 burb

[qksilver]

Finally have all the pieces to convert one of my 72 1/2 burbs into a 3/4.
Everything pretty much swaps out but one question.
I am using the drive train out of a 86 3/4 I got from big unde. It has a hydrolic clutch with a granny gear 4 speed.
The bell housing etc all bolt up but trying to figure out what to do for the trans mount.
The burb was orginally an automatic so no manual trans bell housing mounts.
I want to use the hydrolic clutch so what do I use for a transmission cross member. Is there a factory part that can be used and will the drive shaft angle be correct so I won't tear up ujoints?
Thanks,
Steve
