9” drum brake retainer clips on assembly line, OEM?

Not sure what your pics are showing.
These are the only style drum retainer clip I've come across.
Used to cut them off with dyke pliers, then smack the drum with a hammer to loosen it from the frozen axle flange.

Yea Joey that’s what I remember from when these cars were still 10-20 year old cars, even my a body Oldsmobile had a similar setup if I recall, and they were used during the assembly line to keep drums on while in rotation on line before final drum/brake adjustment

these clips look like little flat serrated washers maybe 20-30 thousands thick with a serrated or splined edge/perimeter. If u look close u can see them tight against the drum and where the stud comes through. Three of my drums have been replaced with century generic 9” drums with a max diameter of 9.060 and the left driver drum is a factory Chrysler part number drum with a 9.090 max diameter and the stock appearing swaged studs, or what I believe to be. Never dealt or done this before so any help is appreciated. Hate asking so many questions but I wish we had sites like this 20-30 years ago. Back then it was calls across country that we paid by the minute and it got expensive at 5-10 cents a minute lol

if it’s to much hassle I will adjust her via rear opening to starwheel to have even drag with pass drum, rears are perfect I’ve adjust them twice for good measure, will re bleed entire system as I want to make sure all the old 10-15 or more year old dot3/4 mixture is flushed with the new dot 4 I have. Did a quick flush a few weeks ago but being in a Rush I think the lines were still contaminated slightly so going to rebleed and flush with a new 32oz bottle of Lucas dot 4 I just picked up. Plus going to flush the power steering again for peace of mind have gallons of PS fluid and semi retirement give me time to play. Again they stop pretty good for a 9” manual car and growing up on these cars I’m aware how drums work, theirs never ending clean and adjust every rotation or oil change (that’s how I was taught) and brake fading, and the shell shock that new drivers have when they drove disc and antilock brakes all their lives. I saw it first hand when I let my nephew drive my old 70 superbee with 10” drums. Poor kid thought he had no brakes. “Unc/me goes that’s why you have a stick and a third peedle lol”. I don’t want to replace shoes (plenty of meat, minus drivers front which I hadn’t seen so can’t attest to) or drums now as I will be upgrading to disc sometime during this resto mod future. Not sure if it’s months from now or over a year. Pending when I fix some rust and do the 8 3/4” rear end, k frame, engine and 4 speed swap
