The original lock rings were cut off. At this point I can pick the best fitting replacement. I would think the one that came with the axle would be matched best but I will measure again and again

Since I just spent the money on good oil I would prefer to know if the fuel pump is in fact contaminating my oil before I ruin the new oil and filter.
I can always use the new fuel pump on this motor or if the 400 ever gets built.
Not to mention this car has obviously sat for many years neglected.

The scissors brake tool is the one i was going to get but i will see if i can cancel my order.

Did the stock Firebird ever use a return fuel line? I don't even have a tank. motor was run off a jug under the hood

And yes no washer was on the brake adjusters when I took them apart

Lube on both ends of the adjuster? Didn't know that was a lube point but i used brake grease on the threads. Should I clean off the brake grease and use white lithium? So the slotted end need lube or the internals on each end need lube?

Are there supposed to be any other washers or clips that could be missing?
Lets assume worst case for prior hack job and lack of experience for me

I do always make sure to clean my shoes, pads, drums, and rotors squeaky clean
