I blew the rear wheel brake cyl when I went to purchase a new one they asked what size drums I have. Aside from getting out the tape measure, how can I find this info? '99, 2wd, 4cyl, manual trans, anti-lock, stepside, loaded, AC, power everything.

 

Don't know which is harder, but yes you should measure. You could also pull the VIN number and call your dealer and have them tell you from the VIN code but that would be a PITA.
