Where Can I Get Rubber Plug In Valve Cover?

'65 Skylark 300, 4 barrel. On the right (drivers) side there is a big rubber plug about 1 1/2" in diameter. Mine is all cracked in the center. Previous owner patched it up with silicon but during my "Rebuild by Krylon" the silicon came out and it looked bad anyway. Does anyone know where I can get one or two of these. All my local parts houses can't find anything unless "it is in the computer". I really miss the shop I depended upon for all my parts but they went out of business. Anyone??

 

Ta performance

 

actually,ive looked also.ive never seen anyone selling the solid plugs,not even t/a.:rant:

 

Best bet, get a grommet with a hole in it and add a chrome oil breather to it.

 

Try Cars, Inc. Group 3 part # cp647 http://www.oldbuickparts.com/catsky/

 

I will look.I may have a decent spare and if I do I will post here........Bruce

 

I think we have a winner. I wanted to order some front bumper fillers from them anyways. Thanks!
