60 GMC V-6 305 Tranny Bell Housing

[KIC]

Hi All

I have an important question. I am in the process of returning my 60 Burb back to a 3-on the tree. Many years ago my older brother blew up the original drag racing his girlfriend in reverse...( don't ask ) .. We had replaced the blown 3-speed with a 4-speed work truck tranny with a low granny gear.

I long while back I had obtained a good 3 speed from a member who was putting in a 350 with auto. Below are the two different bell housings that have different bolt holes although they both work/fit.

Is the first one with the little cover on the rear top the correct one for the 60 Burb 3-speed ?

It has been a hassle finding the correct clutch and parts, but looking forward to making it back to original .
