Recently picked up a 69' Mach 1 that was converted from a 351 with FMX to a Boss 302 with toploader. I'm going thru the drive train replacing parts as needed. I'm working on the driveshaft now and need new U-joints. It appears the u-joint at the trans end is a straight 1310 1 1/16" on both axis. However, the rear end yoke has different size caps, 1 1/16" on the driveshaft axis, 1 1/8" on the rear end yoke axis. Does this sound normal?

You can get u-joints that are crossover, 1310-1330 etc.
