360 to th400 spader

I am posting this question in the short wheel base and the full size jeep forums. I picked up the drivetrain from a 72 wagoneer yesterday. It is a 360/TH400/Dana 20 combination. When I got the driveline out I started to inspect it, and there looks to be a spacer or adapter between the transmission and the engine. It is about 1.5 - 2 inches in length and matches to the back of the engine perfectly. There is also a nose for a starter on the driver's side of the transmission as if to accomodate an I6 or something. I am wondering if they used a spacer between the 360 and the th400 on the early wagoneers, or is this some sort of adapter or something. Any help will be appreciated.

I think the early years they used the TH400 it required an adapter to fit the AMC engine, after a few years they just starting building a TH400 case that fit the AMC engine without the adapter

That's correct. When AMC bought Jeep from Kaiser, there were lots of the old Buick/Olds/Cadillac, ("round top"), cased TH-400's in their inventory. When those were all used up, they switched to a case to fit the AMC engines without adaptor. My '76 Waggie had the AMC case. My '70 has the BOC. I suspect somewhere around '74 is when they switched.
