Does anyone know where I can get stock brake calipers for a te38. Specifically a 1977 Toyota Corolla wagon. The auto parts store has them listed but they are completely out of stock everywhere. 
 

 

That link doesn't work for me..

I could probably score you a set at the local wrecker, but they will be old, rusty and probably seized... You'd be better off to rebuild your own.

I've just bought these for my KE70, they'll be fitted over the Christmas break.  The quality is superb!

The Dynalytes fit on 13" wheels, the bigger Dynapro calipers need 14".
