86 GLHT: rear brake self adjusting arm: where to buy?

[Clay]

The self adjusting arm on the passenger side rear drum brake of my 86 GLHT some how got mangled beyond use. Ive tried to buy a new one from the local auto parts stores (napa, autozone, advanced, etc), but for some reason they think the GLH cars have the same rear drums as a "normal" omni (ie regular omni = 7" drums, GLH = 8", approx).

because of this I ended up buying brake shoes for a Dodge Daytona as they were the right size.

So, 2 questions then: Does anyone know a way to get the proper self adjusting arm from a parts store? or does anyone know if they are available at the dealer?

thanks!

could try just buying one from a Daytona, since they had rear disc...
