My 1988 has a Dana 44. A while back a shop replaced my diff. The clutches have failed. There is a thin shim in either side that's damaged. I'm struggling to identify the correct parts to buy. The diff has something I'm pretty sure is called Cross shaft preload assembly. There are two t shaped plates that sit between the spider gears with 4 stiff springs. When I took the clutch packs out there were only 4 rings with ears and there was just a flat washer, not the spring washer. whereas every kit I see shows an extra tabbed disk with a hole in on of the tabs. Chatgpt suggests I just need to order a common clutch kit.

 

Does anyone know what I'm talking about?

You are describing a positraction LSD.  Four springs and t-shaped plates.

The OEM Trac-Lok diff has no such parts.

I'm guessing the shop replaced your OEM Trac-Lok with an aftermarket LSD. This means you are barking up the wrong tree with your parts search.  

 

Start by looking for any identifying part numbers on your diff casing to ascertain the maker then try your parts search again.
