G'day Harko,
Cool photos

. For the crashbox Guide I'm pulling together, I've added a drawing that might help people identify different boxes:
Still needs a bit of work before I finalise it. Looks like I've got access to a red motor crashbox, so will add those dimensions. If you get a chance, I'd love the simplified dimensions and gasket shape for the Tremec to add to the drawing (pretty please

).
If anyone has a Muncie, Saginaw or Borg Warner box floating around, I'd appreciate those dimensions too.
Cheers,
Harv (deputy apprentice crashbox fiddler).
