Trying to understand the assembly process, since Fatalwishes left a FAL receiver.  No, it's not a preferred one - I presume he got in a sale and it was cheap.

Installing them is straightforward: grease the locking shoulder shaft, squeeze it in with a vice. Avoiding hitting it with a hammer.

As for selecting the correct size, you're going to need go and no-go headspace gauges.

And an appropriately sized pin set or something similar...

No filing you need to find out with the pins what size locking shoulder you need. So dont intall one if you all ready have one untill you know its the right size.

Any videos or graphical FAL for Dummies?

Keep a few things in mind.....forster and clymer 7.62 go/no go gauges are to different specs. A standard Forster go is 1.630", 1.634 is no-go. I believe a clymer no-go is 1.636.

Determine which you have, use your pin gauges , and aim for FN minimum (1.632") ......assume there will be .001" setback. FN max is 1.638"....

I have a bizarre method that has worked well on every FAL I've ever built.

I use a 1.634" forster no go (extractor removed), then find the pin gauge that will just allow the bolt to lock. To that pin gauge dia. I add .003" (.001" setback + .002" (diff between the 1.634" gauge and the 1.632" FN spec) ). That gives you the locking shoulder size you need.

Every time I've done one just using a 1.630" "go" gauge .....and then adding the .001" for setback, I've ended up with tight headspace that some surplus didn't care for

I kinda understand how Go/NoGo gauges work - what I'm looking for is a start to finish guide, not helpful tips.  Y'all have been very helpful, but I'm looking for a graphical guide or a video.  It's ok if there's not one, but that's what I'm looking for.

Gus Norcross wrote a simple how to build a FAL article long time ago. Another is  look for the Gunplumber's assembly  guide in pdf. Last, is the AGI's video on the FAL.

Thanks much!

This was always the most tedious part of the build when I used to help my friend, follow the advice given and be patient.

I prefer an arbor press for installing/uninstalling locking shoulders.  

Considerably more control/feel than most methods.

THAT is exactly what I'm looking for.  Thank you.

This will give you an idea of setting headspace, but I'd use actual gauges.  And you can file the locking shoulder to size since it's completely hardened, if you're good with a file.  Otherwise just buy the size you need.
