I belive the S-10 measurments differ some from those pictured on the Camaro chart. I can measure my S-10 tonite and get back to you. I do know the big hole in the bell housing is same as all post 55 Chevy cars/51 trucks.
I'm in the middle of installing S-10 unit in my 46 Chev pickup. My problem is that big hole is smaller on this old truck so have had an adaptor made. Lots to measure and consider on this swap but well worth the minor head aches.
Let me know via email if you still need these measurments.
