I believe that this is a T2 bell, but I also have another bell with only 8 bolts, missing the two on the top and bottom.

I'm trying to get an adapter from GForce, and they say that this is not a T2 bell.

The depth is supposed to be the same as a T2.

 

There is a problem with the orientation (rotation) of the trans vs the engine with this bell housing. The access plate on the bottom of the bell is parallel with the bottom of the engine. But the adapter from GForce rotates the trans 10 degrees counter clockwise so that the shifter is closer to the driver. Any comments on the rotation of transmissions for various years and bell housings?

 

Looks t2 to me.. Which T2 bellhousing does G-force want S4 or S5??? I think they are different...

 

That's a Series 5 bellhousing. Series 4's don't have the two bolts, top and bottom, but they are essentially the same. I've used S5 bellhousing on S4 transmissions before with no problems just make sure you add extra silicone where the extra bolt holes are.
