Brake booster recommendations

[Sonny]

I have a 1970 Belvedere that originally was a 318 car with 4 wheel drum brakes. I’ve upgraded to disc/drums and want to add a brake booster. Current mc uses a single straight rod bolted to the brake pedal and I have 15” of vacuum at idle. I’d prefer the single diaphragm over the double ones.
Any purchase recommendations appreciated!
I already have the mc plate on the firewall see photo.

Gentlemen,
I've used the Ram man: therammaninc.com
I bought the rebuilt Bendix tandem booster, but he presents Bendix, both single and tandem boosters, Midland-Ross or as an alternate supplier, there is Booster Dewey. Google it for the web address. Both suppliers can furnish all the pieces and parts needed including the master cylinder, brake hoses etc. Either can supply all you need. Just my opinion of course.
