Power brake booster grommet - 1968 Merc.
 

Need to replace the grommet and might as well change the booster check valve on my 1968 Cyclone GT. Cannot find a listing or confirm a Dorman number anywhere with specs. The hole on the booster is 1 inch, and the check valve is .85 of an inch.

If I can get a Dorman part number or another brand, I could likely buy locally. The check valve still works so I'm more worried about the grommet at the moment.

I found a Dorman part number: 80191 but there are no specs on size at all even on the Dorman website. Cannot confirm if this will fit.

DORMAN is off-shore.
