I bought a SSBC conversion kit for power brake system I currently have a manual drum system.
I need info on a booster mounting bracket,for mounting the booster to the firewall,if anyone has
one,or knows where I can buy one please let me know

I would think that SSBC would have that bracket, but if you need to find another avenue, I would try Ames, Classic or any of the major 1st gen parts vendors.

And or, try to find something locally, maybe an original from a recycling/junk yard?

Just a few ideas?

You may want to check the FAQ section, (or searc some of the posted topics here) as I believe there has been some talk on this conversion, and if I remember right, some were not so impressed with the system? So before you get too much further... maybe look into that aspect of it all?

The correct brake booster will have the bracket permanently attached.
