I just put 11" on mine, had 10" The cylinders "look" bigger on the 11" but that's just a visual observation.
Me personally I'd probably just order from DR Diff but I have no idea where he gets them from...

I just rebuilt the brakes on the 9.25 in my wife's duster. Raybestos from RockAuto was still made in USA... I ordered BrakeBest wheel cylinder rebuild kits from O'reilly and one was an old stock Made in USA, one was new made in China; BrakeBest is made by Carlson and after doing some digging on Carlson's website it looks like they've offshored all of their manufacturing. I used the USA made wheel cylinder rebuild kit to build out a spare have on hand.
To my knowledge, no brake drums or rotors are USA made, most all of them come from communist China and the final machining is done here with some excepts such as Brembo replacements for Toyota's coming from Brazil.
A friend of mine who's a local car guy is the manager of my nearest O'reilly's, he's just as frustrated and listening to the problems he deals with from the parts store side, it's just as frustrating for them as they're struggling to just get most parts whereas hobbyist like us are struggling to get quality parts.

I appreciate your input. I understand the parts shortage. My girlfriend's son was manager of a local O'Reilly's... He said it was hell trying to find parts. I'm really happy for him that he recently landed a sheet metal workers apprenticeship gig in a nearby town, but I sure miss those store manager prices. LOL Luckily the drums are in very nice condition, and even the brake shoes are still like new. But I'm not trusting the cylinders since the rubber boots have shrunk and are in poor shape. I just power washed the drums and the backing plates, and repainted them. Is the number on the cylinder what I need to use for cross-referencing or ordering?

If you feel handy, rebuilding wheel cylinders is perhaps the easiest rebuild-able part on a brake system. When you order wheel cylinders (or rebuild kits) I'd suggest going thru RockAuto's website and drill down by the car you have and you should see the different parts based on brake shoe sizes. If you try the big box store route, I'd start at Napa personally or an old school independent shop if you have one.

There is no reason to get new cylinders just for the dust boots. As far the rubber parts are available I simply would replace those. Rebuilt kits with rubber parts are available. Well, they are/were available in Venezuela at least, so I guess why not in USA.

Since I will never sell my car as long as I live, I had the factory original master and wheel cylinders all bored and sleeved with brass to the original ID. Cost was $300 10 years ago.

Damn....  Looks like rebuilding the cylinders won't be happening. One of the alum. pistons is shot because of corrosion. Screw messing with a rebuild kit... I'll be looking for some new ones.

yep...I've seen that before.
I don't know if what I'm doing is wrong, but starting a decade back, whenever I buy a wheel cylinder, I disassemble it, clean and paint the body with engine paint. Then when I re-assemble them before installing them, I grease the aluminum piston with synthetic/rubber safe grease (I use Super-Lube), and I also pack it between the piston and outer rubber seal. I do this to keep moisture out, with my thinking that moisture is what starts and provides the fuel for corrosion.
Since doing all this extra work, I've yet to replace one of those wheel cylinders prepped that way.
edit - And I also use DOT5 in all my old cars that don't have ABS. I realize that there is a current thread debating it, but I've found that to do it w/o problems later on, the brake system has to have all new seals (beaning new or freshly rebuild calipers & wheel cylinders) and the lines be flushed with solvent before essentially doing a first/fresh fill and bleed with DOT5.

I'd try to clean those anyway... maybe the results could be surprising! LOL

Looked up 69 RR rear wheel cylinders on NAPA's site, $17.98,
how does that compare with Dr. Diff?
Not trying to undo the good DR's value to our sport, just wondering.

PS. looked up the Dr's price....better than NAPAs, my apologies Doc

PS. looked up the Dr's price....better than NAPAs, my apologies Doc  $30 (+ $7.85 shipping) seems reasonable, i didn't even bother price checking on other sites. Hell, I wouldn't doubt if a rebuild kit mentioned by a few costs more (and i won't bother looking around to find out). I'd try to clean those anyway... maybe the results could be surprising! LOL It's grease caked with some mystery crap...and that alum. cylinder has corroded to the point of 'not usable', but you can have the pair for $29.99, plus shipping
