Carb heat shield . . . anyone try this?

I ran one of these when I had a Carter carb on my old 340, worked great:

The fuel would still boil out over night but it solve the embarrising no start issue when I would stop and get gas or get ready to leave a car show. It is specially made for the boil over problem that todays fuels cause.

I bought one of these for my 1965. Wrong bolt pattern. My 1965 carb bolt pattern is approx. 4 1/4" wide. The holes on this part are approx. 5 1/4" center to center.

I also tried SCE 352.

Good looking part for a great price, but same problem.

I think the Trans Dapt 2446 would fit since it fits both the Holley bolt patter as well as the narrower early Carter pattern. But it's not cheap.

Still looking for something affordable that fits the early pattern.
