4speed questions

That’s either a 64 or 65 transmission. The Ball and Trunnion flange on the rear is a dead giveaway. Should have a 3.09 first gear as well. The 64 and 65 slant bells are somewhat different, mainly where the bracket with the ball for the Z Bar is mounted. IIRC @Bigboy 68 had a 64 bell as he was looking for a 65 bell. I saved the slant bell and 833 for a possible future project that I removed from a 65 Signet. As mentioned those slant 4 speed bels aren’t the easiest to come by.

EDIT: those transmissions are a stout unit with the extra bearing in the tail shaft. The B Body variant was used behind Maxi’s and Hemis in 64 and early 65
