1968 Anyone else got front drums?

[dalorzo_f]

NPD show a 2140-5 and 2140-5R (rebuilt) for 68 w/front drums. The caps are different.

-5 has two low round bumps in the cap,

the -5R shows taller sloped bumps on the cap.

Anyone know which (if either) would be correct for the GTCS? The -5R matches what came off the car and the parts "looked" like they had never been off... but who knows.

I have the second one on my car.....5R. Matches mine and it has not come off car....Just rebuilt.

If I were to guess either will work. The 5R is rebuilt and the other is new. The 5R looks like a original style. Marty
