5mt crossmember schematic

[SoCoNoHa]

I'm looking for a diagram or schematic or measurements or anything that would help me construct a crossmember for my 5mt swap. I've only got jack stands and my SVX is my daily babe, I'm afraid building the cross member as I go won't be an option.
I've read the hardest part of the swap is the pedals, but I've already installed a set from a 3rd gen legacy (2000-2004US) and almost no modification was required. All that's left is to modify the rear diff and fab up a crossmember.

If push comes to shove I'd be interested in purchasing a x-member if someone has one kicking around.

Update: My transmission has had the radish, so it looks like I'll be doing the swap sooner than expected. Once I get a crossmember mocked up I'll post pics and specs here, and will record in detail the process of converting the rear diff.
