84 K20 standard drum size (14bsf)

[Jake_S]

I know I can pull the drum and measure, but I'm being lazy and its sleeting.

What is the standard (or most common) drum size used on the 14 bolt semi-floater? I need to order new wheel cylinders, shoes, and hardware kit.

There's just no good way to know for sure without measuring. It could have either 11" or 13" from what I've found.

Call the dealer and give them the JB* number off the RPO list in the glove box - if it's still there.

They should be able to spec the parts you need from the RPO code.
