Any 833 4 speeds to avoid?

There's only two, A bodies are short. If it wasn't for the shifter pad location, you could actually use a long shaft in an A.

"Some guy" made a bracket/ adapter to do just that, but it was big, bulky, "work," and I think required some crossmember mods

This is a good read

Top tail is A body, lower is 70 / later B / E body. Earlier B body tails only had the front shifter mount pad
