Drum size?

[Wicked Wolf Auto]

One of my drums is warped on my 97 gmc 1/2 4x4. Looking at website it shows an 10" and 11" version is there anyway to tell the differance without pulling the thing off again?

umm, get a tape measure, and get on the ground and crawl in behind the tire and measure it?

Or just take it off again. Doesn't take that long. It's probably stamped into the drum.

how big of a no no is it to change out just one drum?

Easy.

10" drum on the 10-bolt.

11" drum on the 14-bolt SF.

I wouldn't do it. One drum will heat up and fade faster than the other and cause uneven braking. Up to you though...
