1978 T150 Challenges

I have been going through my 1978 T150. when I put in the mainshaft retaining snap ring it was loose, so I held it and thought I would use a hammer and bend it back a little tighter. Well, I lightly hit it once and it split in half. So I think, I will just buy a new one. I have been unable to find the actual part number for that item. Going through more diagrams that I can remember. I have yet to see a listing with the actual part number for that item. I tried the J8124935 but it just hangs on the shaft because it is so oversized. I also saw a site that said it was the 8126813, which is the front bearing retainer snap ring. Does anyone know the actual part number for the "mainshaft Retaining snap ring"? In most service manuals it is listed and 1 in the parts diagrams.

Thank You

Still not a winner. Just had my new clips dropped off, the J8124934 and they like the J8124935 and the 8126813 are not the right part number. Does anyone have a factory parts manual for a 78 T150 they would reference.
Thank You

You might try calling Novack. They also sell trans parts. They may be able to get you what you need over the phone.

Novak like all the others only has it in a small parts kit. It must be one of those parts that is hardly ever replaced on it's own, so not one has ever had to research it. If I did not have the transmission done I would pickup the small parts kit, I did not believe it would be this difficult to figure out.

I appreciate it. I added a pic, but not with a ruler or dial caliper next to it. it looks to be .092 thick the ID is around 1.305 being broken it is just somewhere in that range. The width of the ring is .163 and the outside diameter is around 1.682.. I really appreciate the help. I found what may work but it is a manufacture and cannot find it at any retailers.
Thanks

Cool I'll look when I get to work tomorrow (that's where my jeep is) I broke one when I was taking it apart, but I dont think it was the one you need.

Garage
Rural hoarder type transmission shop or ole time auto salvage yard with '60s and '70s Ford pickup trucks, some of 'em had T-150s (2WD) with a tailshaft on the back end. Sometimes you can find the trannys taken apart ready to scrap out (not needing to buy the whole deal).

Since you're doing a rebuild, you probably need a small parts kit. Why don't you purchase the kit Novak has?

I think I have what you need . The Id and od dont match but are close so I am assuming it's because your is broken and mine is not. But the other measurements match.
