Ok this may sound dumb but I'v been a car guy a long time but this is my first Y Block. The car is a 57 an old drag car It has a bad condenser but I have no way to ID the dist. I think it is an old Mallory but it has no markings on it. I don't know what a one stock looks like. This one has a large condenser on the out side also were can I get old electrical parts The coil is a blue streak air cooled if that helps       

Sounds like Mallory unit, Summit has tune-up parts.

I actually looked into this and there are Petronix kits for the Mallorys.
There's the other option.

Spud,
I have some Mallory parts:  New Napa Points, Original two piece cap, Original Mallory Red Coil, NOS Mallory Ballast Resister. Not cheap but very good stuff.  email me if interested and I can send pictures.  Also a picture of your distributor would help

Also I might have the condenser you need.
