A 61 short box driveshaft is going to be pretty hard to find in it's self.

The trans Am uses a Moog 534G or a better grade version of that U Joint at the rear.

There are a bunch of yokes that fit fit the 700R4 and have different U joints.

Most 61 Chevy C-10 use the smaller 369 series U joint that fits most Chevys from 55 to mid 60;s There is also going to be a difference between the driveshafts for 3 speed and powerglide and the 4 speed. https://www.rockauto.com/en/catalog/...sal+joint,2392

A 90 Caprice with a 700 R 4 takes the same 534G base U joint that the Trans Am does. That should keep you to the same size U joint on both ends without a hassle.
