Getting ready to put a disc brake kit on my -69, and when dry fitting the parts I noticed that there was no seal to go between the booster and the master cylinder. As far as I remember, there should be a tapered or cone shaped rubber seal here. Does anyone know if this seal is needed, and in that case: does anyone have a part number for it?

I had the same question not too long ago.

Send an e-mail to the TC'r who responded, or actually click on his name and give him a call or go to his web site....good guy to know.

Thanks! Will count all parts this weekend, I'm sure there's more I need to order from him.
