Hello anyone out there know where I can find a snap ring for the drive axle that goes inside the differential on the driver's side?

 

I'm guessing you are working on a Toronado, but what year and transmission?

 

It's a 79 Toronado with a TH325 Tranny. I spoke with a Summit Racing guy yesterday regarding this situation for about 45 minutes. I think we might have it worked out, however you might have a suggestion and I would welcome it as well. This part that goes into the differential is a flange on the outside and has a spine shaft with a groove on the end of the shaft. This inserts into the differential and the flange on the outside connects to CV Axle with 6 bolts approximately. The Summit Racing guy said that what holds the flange with the shaft inside the differential is a C-Clip which I ordered from Yukon Gear & Axle. What do you think?
