[DeTomaso] Shock tower crossmember measurement

[Thomas Borcich]

Guys, can anyone give me the standard measurement for the rear crossmember shock tower? Pocket end to pocket end? 
My bolt holes are very elongated on both sides, actually look like ovals. I'm sending my car
off this week to have the wheel house damage repaired from broken half shafts and would like
to have the crossmember bolted in relatively close to a stock measurement before the welding starts. 
I have a December 72 build car.

Thanks

Tom
