Dreaded clunk when turning
Here is what the 7 1/4 looks like, see how close the differential spider pin is next to the ring gear.
Might be just as easy for the OP to mark and pull the 2 bearing caps . . and if any shims there mark and get them back in where they belong. Then pull out the differential carrier and get it up on the workbench. Leaving the pinion gear/shaft in the rear end housing.
Here you should be able to see that roll pin and drive it out. If not pull the ring gear off of the carrier, drive the roll pin out. push out the diff pin and install your new diff spiders and side gears and reassemble in reverse.
