Hi, the c-clip went out on my rear axle which cracked my differential and sent my axle and tire into a nearby field. I decided now would be a perfect time for a rear end swap and pulled one out of a 2002 sonoma 4x4 crew cab (my truck is a 2001 s10 xtreme extended cab 4.3lt). The new rear axle is a gu6 g80 with disk breaks. Ive gotten everything unbolted and prepped the rear end too go into the truck but I just realized that the connector from the driveshaft does not match the one on the differential. The one in the driveshaft is circular while the one on the diff is rectangular. Do I replace the connector in the differential, take the driveshaft too a shop, or buy a new drive shaft. Im 17 with somewhat limited funds so any advice is appreciated lol.
