stock rear drums

[broncosbybart]

The rear wheel cylinders use little 'extension rods' from each piston to the brake shoes. If one or both of them is missing, the pistons in the cylinder will overextend and leak severely/dangerous. Only other thing I could think of would be drum size. EB's used both 10" and 11" dia drums. Are they mis-matched? Net effect would be the same scenario as well. The 11" drums were narrower, so I think that'd be hard to screw up without noticing.

Let us know what you find.
