Wheel cylinder info needed.

[74RR]

I bought a set of backing plates and drums. The drums measure 9" and the pads measure 2.5" wide.
I need wheel cylinders for these and this is the only information I have no idea what they came off of so when I hit up the local Napa or O'reilly I'll probably leave empty handed.

Can anyone help me out with part numbers or any other info I should look for so I can order these up?

Thank you!

I hope you can tell NAPA what year and vehicle you have.

Since you have internet, why not check online. Autozone lets you see PN and what local stores have the PN. I think you see the same screen the counter guy does, so I just go to them w/ their PN. NAPA seems less web-centric and their stores seem more independent, but last time I needed a rare PN, the store did have it on the shelf per the web.

Check rockauto's site for many manufacturer's and PN's. You'll likely buy from them once you see the lower prices, if you buy enough to make the shipping worth it. Otherwise, ride them for free info like I sometimes do and shop those PN's on ebay and Amazon or NAPA.
