Hi,
On an original temperature sender for a 1950 truck what size is the port drilled into the head? 3/8"?

I have an 848 head on a 261 (1962 head and engine) with an enlarged hole for an electric sender. The 62 hole is 1/2". However, I used a bushing to get it from 1/2" down to 3/8" in an attempt to use the original gauge sender and the old '50 sender is still flopping around in the 3/8" hole.

Anybody else have this issue?
