Thank you both for the info.
I bought it off a guy who removed it from a 1970 Barracuda convertible running a 318.
He said it was a good gearbox so I may use it as the earlier boxes have wide ratio gear sets from info I have read.

Somebody must’ve swapped a later dual mount tail shaft housing onto it.

It does have the dual mount tail shaft I did research enough to know that was the type I needed for my E body. Made sure that was on there before I bought it.
You could be right may have been swapped at some stage in the past.
