Those are for a Balcrank glass body Randy....it would be very difficult to find a body to put them on.

You could mount them on a 13 1/2 inch Gill body and hope to find a Balcrank body some day! That would work just fine. They look like really nice lenses!

Or a 13.5" aluminum body.

Some original glass bodies have dimples in the correct spots for these lenses - but you'd need to punch/drill them out to make the body work.

Later . . .

They would look fantastic in a red or white ripple!
