TH350 Bushings Questions

[YourBuddy'sTruck]

So I have a TH350 that I'm rebuilding. 1970 C20.
Learning as I go and doing okay so far.
I see wear on my Thrust Washers as they are steel and copper. (or bronze?)
Ordered a new set of Thrust Washers and expect them to be Delrin/plastic.
Ordered new Torrington Bearings that I may or may not need.
(old ones look good)
Also, Forward Sprag was toasted! Rear one looks great. So ordered one Sprag.
Bushings? I know nothing of the bushings?
Pulling them out. Pressing them in. Something I've never done.

If my Thrust Washers are worn, should I expect the bushings need replaced?
I know that's two different forces, rotational and load?
Is there a way to measure the bushings? Diameter compared to shaft?
If so, how much +/- for fluid?
Can you point me to a thread that already covered this?
I've been reading more than writhing here for a couple weeks and learning a LOT!
Any tips, thoughts, info on bushings will be much appreciated!
Cheers!

Btw...3 weeks ago I couldn't find good swap rebuild.
Now that I'm this deep, a guy shows up on Craigslist that I WISH i'da met 3 weeks ago?!?
