help needed

I think I answered this once before but I'll give it another try. Like '64 Cuda said, the frame bracket is early A-body but nothing else is. The crossmember is '64-5 B-body, the Z-bay looks like a later A-body or maybe F-body. The shifter looks like a combination of a 3 speed A-body stick and 4 speed mechanism. The Inland shifter has a T-handle reverse lockout trigger that moves a braided cable running down the center of the shift lever into the mechanism. From what I can see on yours, it's not that design. The rods look too long for an A-body transmission but that's just going by the photos. Measure the length and maybe someone will take the trouble to go measure theirs for comparison.
