This is the only one I could find. I remember that I had it blasted and then powder coated. Obviously it isn't perfect, but not too bad. I also found a spare lid as you can see. I'm not 100% certain, but I think the other three in that one pic are possibly from a 2bbl 300.
Here are the pictures of the ones I have.2 are for the 4 barrel,one is for a 2 barrel and one is original Olds.That one will be $100. for anybody that wants it.I must have sold all the covers,do not have them anymore,So Jim,if you are interested in those 2,I'll take $50.00 for both and 20.00 for the 2 barrel,plus shipping.Bruno.
