PCV Valve Grommet Hunt
So, I need to replace the grommets on my 1969 350/300hp valve covers as they are worn and cracking. The ID on the PCV is .75 and the hole is ~.93in. All grommets I have been able to find seem to be 1.22 or 1.25in OD grommets. Anyone know of a place to get them? I would rather not replace the valve covers as I am trying to keep most things original if I can.

So, after a ton of research, I found the correct size:
23/32" ID X 1" OD
Ordered from my local NAPA: CRB 29109 for 2.99 each
Other possible part numbers for this (According to an ebay listing, take with a grain of salt):
GV9
2P1004
PCG100
76-1500
CV5012C
1901-511355

I had a heckuva time finding them as well for the '76. ended up finding them at an old hot rod shop. none of the chain parts stores had a clue...I have been grabbing various grommets from the junk yard every time I go so I have a nice stash now. not having a lot of faith in the made in china ones I bought lasting as long as the originals but we'll see.

So, I picked them up today and yes they are the square style but they fit perfectly and will work great. The old ones were original and felt like hard plastic and no longer hold the PCV and breather upright. These were nice and pliable and went in with no issue
