What New Brake Shoes for 83 avanti?

[MikeValent]

3771 has one leaking rear brake cylinder. I got new cylinders for both rears from SI. Might as well have the brake shoes replaced, but don't know what to tell the mechanic to get. The only reference I've found is that "The rear brake shoes are a #228 for an 11"x2" drum. To tell the auto parts store it's a rear brake shoe for a 69 Chevy Caprice." Can anyone tell me if this is correct info, and if not, what shoes will fit?

If you had a wheel cylinder leaking you do need to replace the shoes. If they get brake fluid into them they will start to disintegrate on you. If the number on your shoes is 228, they are for the rear of a '69 full size Chevrolet. The NAPA number is TS228. Other parts suppliers should have an easy cross reference for that if they use a different brake supplier than NAPA.
