SM420 PTO

[Diesel42]

Can anyone identify this PTO(Yellow) and/or the adapter/spacer(aluminum) that bolts it to the GM SM420 tranny? I have the same PTO unit but need to figure out the maker and model #. I am looking for the adapter spacer which allows the angle for the front pto driveline to clear any front crossmembers on its way to the winch. Thanks

Have you googled the casting #'s on the aluminum adapter?
This looks sorta like your pto

Yes, with no avail. I found that one a few days back. It is different.

I run Toyota PTOs and without a spacer the PTO is just inside the frame rails. Before I invested too much time and energy I would be sure there is enough room for that spacer. Unfortunately the two last posters in the linked thread haven't been on Mud for a while the one going to buy the spacer said it should work but only had pictures from the seller.
Many years ago I bought a couple of SM420. This was around the time when a new adapter to the Toyota one piece transfer case was coming out. Believe this was based on an article in the TT. Danny Warden was the one doing the conversion. I contacted Danny and bought the old adapter. The tailshaft on the old adapter was full length and would allow the use of a Toyota PTO. The tailshaft was worn on the part inside the transmission and would have required a machine shop to build it up and machine it back to spec. I ended up selling the adapter and SM420 to a friend because I didn't have the funds at that time. Not sure what happened to the adapter. The friend pasted away years ago. That would have been the best way to run a PTO. With the PTO further back could probably cleared any crossmember easier.

So far I. leaning on the pto being a Dana/Spicer. The adapter is a 30 degree but not a Chelsea. Still trying to identify these pieces. I need the adapter, but almost impossible to find if I don't know what to call it
