I decided to post this after numerous seaches turned up nothing. That is why the subject is so crazy. I am hoping it will turn up in a number of searches.

I made my way to advanced auto today and purchase a set of exhaust donuts for my SLP JUNK headers. They let me sift throught the gaskets until I found the right one. Here is the Part Number so right it down.

60986

In the future it may change to this number according to the packing. 12-1184.

It says it is for a CHEV..GMC V8 1965-91n (Sintered Metal)

Hope this helps

 

Thanks for the info..

How much were they ?

 

Great info, But is this for the 1 5/8 or the 1 3/4 size headers or do they have the same flanges and or y-pipes?

 

I have the 1 3/4 pipes, but I think the collector and y-pipes are the same for both 1 5/8 and 1 3/4 headers. I do not think they were more than 4 or 5 dollars a piece, and they are pretty good quality.
