looking for dimensions for rear drum brakes... having a hard time finding them

 

need inner diameter for ea82 stuff and inner diameter for ej18/ej22 rear drums.

can you stop in a store and measure them? used ones might be a slightly different measurement, have been turned before? i think i have some EJ drums lying in my garage somewhere, but i don't have anything accurate to measure them with.

I guess what I want to know can be determined with measuring shoes.

 

drums are special order. the ea ones at least... I really don't want to pull mine yet, either.

 

 

if any one just knows what size they are "called" like are they "10 inch disks"

 

 

found something EA drums are 7 and 3/32 inch... I assume this is overall diameter

 

Gary, a "close" measurement is fine...
