You will want to hone out your small pinion bearing to make a setup bearing when you set pinion bearing preload with the SPS. Then replace with your new bearing when preload is right. It makes it way faster and once you get close .001 is like a mile so get ready to be down to the nats ass.
Correct me if I am wrong on your #s
.023 pinion shim
.006 BL?
Can you thin the marking compound with gear oil and apply as much load as you can so there is a more readable pattern please.
Also, there is nothing wrong with being on the tight end of BL if you can get away with it. Common...
Out of a 1983 with the mount. Pitman arm will need some work if you are using that (pictured)

Excellent to know! I was in a rush when I discovered my nitro twist and didn't even ask, thought I could just zip through with a drill bit like I had done on the stock and nitro stuff. Wrong!
Nitro Twisties.
Oh yeah we have had issues with stock shafts and Nitros and had to go to an RCV.
If you go the RCV route you will need an end mill to take the drive flange holes to 7/16". RCV stuff is super hard and even the best drill bits won't touch it.
