Transmisson Gear Set Interchange

[V8COOPMAN]

I'd surely like to know what the case on this side-shift transmission came out of with that cast bolt flange on the rear. Corsair-Kid....can you turn that trans upside-down and look for a ??-7006 number cast-in at bottom rear of case? They may be covered by caked grease. There should be two prefix numbers before a -7006. Can you see TWO prefix numbers like that? Can you read a serial number STAMPED into that flat, rectangular pad at TOP, Front of trans case? DD
