I have a pitman arm that I need to ream out for a 1-ton GM TRE. What is the taper and what depth do I go?

The taper is 1.5" per foot and you need to have the TRE in hand while you are reaming. You can either measure the TRE with a caliper and transfer and mark this measurement on the reamer or you can just ream the arm a little at a time and test fit until you get it right.
Yep, snap-on r121 is a 7* taper. It's what I used. Keep trying the tre until it fits right. If you get the snap-on reamer, use a heavy feed, and cutting oil. The snap-on reamer seemed like a POS when I got it, didn't seem sharp at all. I'm used to having to handle reamers very carefully, so you dont slice yourself open. I read on pirate to use a heavy feed with it, thats what I did and it worked perfectly.
