Finned Oil Breathers

I'm looking for a source to use with an old set of Cal Custom finned valve covers for sbf. I would like to find some that match the valve covers but they need to be twist on. Closest I've found have been some Mooneyes covers that would look pretty close.

Anybody know of a source or have an idea on something else that would look good. Below is a picture of the Mooneyes.

Thanks

 

Those don't screw in or push in. They are aluminum covers that are held onto YOUR breathers with the set screw near the bottom. I got mine from O'brien truckers here on the HAMB. I think he is an Alliance vendor offering a discount to Alliance members. Measure your breathers or find some screw in breathers that fit their covers.

 

I had one of these on my flathead. They really look like ****. They are bulky, and as the breather ages they tend to pull the breather off because they are heavy. If someone knows of a lighter or better thing to use I would like to know. Because in my opinion these really ****!! Quality is poor sand casting to.
