Hi. I've got an ali bellhousing for an essex V6 engine thats been modified to fit a... well that's just it, I'm not 100% sure what gearbox its been modified for! I've attached a picture to help. The dimensions of the four bolts are approximate (4.5" from top-to-bottom and 5.5" ish across the bottom).

My first guess is a type 9 gearbox because of the hole drilled in the top for the peg of a type 9 to fit into... but I can't be sure - anyone got any ideas?

(could it be for a type E?)
