Currently out of stock at RockAuto, but this will give you some part numbers to look for. 1973 DODGE DART 5.2L 318cid V8 Power Brake Booster | RockAuto
Most auto parts stores (NAPA, O'Reilly, Autozone, etc.) should be able to look one up for you.
I have a 360. Shouldn’t matter though. I went to said auto part stores and they said that part was discontinued basically. They told me to look at eBay. However I’d rather buy new instead of used. But maybe your part numbers will help. Thank you
