Believe their was a early 1/2" thick adapter then switched to 1".

On the way there
I bought an SM420 several years ago that came with a 2 inch thick adapter that looks suspiciously similar. It also had a stepped spline main shaft that had been swapped in, that made a clean adaption to Toyota 10 spline case. Brian Sullivan has it if you want to contact. So it was an available product at one time in the past. I vaguely recollect that advanced adaptors had made the special main shaft for the SM420.
Probably the first person in the world to put a sm420 in a cruiser was Earl Warden, and his adapter plate was about one inch thick. I don’t think you could go any thinner because you need to have two bearings on the output shaft and one of them is in the plate.

You may be right. I was going off a old article that was in the TLC Trails. Believe it was Danny Warden who was making a new SM420 adapter. He showed the one old he was removing. It had a plate I thought was a 1/2" but may have been 1". I just remember the one old had a hybrid shaft that was full length. Who ever it was I contacted them and bought the old adapter. Wanted it because would work with a PTO winch and Fairey Overdrive. Never found a decent SM420 and sold the adapter years ago.
