Today I discovered why my Delco Moraine power brake booster is having troubles, the main problem is a broken diaphragm, there is a small crack on the rubber... unluckly I haven't found a new one in the rebuilding kit I bought... does someone know where I can buy a new one or a good used one that I can use?
On the schematic the part is letter U.
Thanks in advance for any help, I will appreciate it a lot, that problem is keeping my almost done restoration project stuck...
