G'day Harko,

Cool photos 8) . 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 :D ).

If anyone has a Muncie, Saginaw or Borg Warner box floating around, I'd appreciate those dimensions too.

Cheers,
Harv (deputy apprentice crashbox fiddler).

G'day Mick,

Do you mean differences in the gearbox body, or the extensions? I think its only the extensions that varied for a given box. In the picture above, I've given the different extension lengths available:
Powerglide can have a 9" or 12" extension.
T350 can have a 6", 9" or 12" extension.
T400 can have a 4", 9" or 13" extension.

Cheers,
Harv
