I have a non Thunderbird frame that does not have the hole for the SU carb.

Its unlikely I'll find a frame here so might just convert the one I have.

Would anyone have one that they could give me the measurements and or a copy of a tracing?

Exhibit B is the bike:

Picked it up as an unfinished project, mostly there except the outer chain case, the SU carb. Its a 1953.

Motor is usual " was rebuilt but no docs"

Cheers John
