Back then the TM fairways were 400 and the rescue was 395Probably. I have never heard of a .395 bore though, so you would need to make sure you can get a shim to fit. Most fairway woods are .350 or .335 and that would need to be a pretty large shim. Are you sure that hybrid is not a .355 ? Most current hybrids are .355 or .370.
The bubble shaft was an odd bird though and might be a strange bore size.
