Call MSD tech line. I have had them rebuild a couple of their distributors and a couple of old style 6AL boxes. The results are great and the prices weren't bad. They have guys there that do nothing but rebuild their older stuff.

ALL - bar none, of my MSD boxes that went back for repair have failed and most failed faster than when they were new OOTB.
