I figured the Bosch shaft was a metric size. Never tried to fit the original 
TR250 pulley. This was the night before departure!

Moss has a kit which TRF also had. Got one from TRF the day before. Looked 
like more work than to simply fit individual connectors. So, time being and 
issue, I went with individual connectors.

In a rare moment, I remembered that I had a number of Lucas connectors of 
the proper size. Probably from use on a later TR3 generator way back in the 
very dim past. I believe British Wiring still has them.

But then, a rebuilt Lucas unit would have worked well too. There is/was no 
additional electrical load on this car, just original equipment. The Lucas 
rebuilt I got from AutoZone last year for an MGB was 40 dollars cheaper than 
the Bosch and also with a "lifetime" guarantee!

It was a great trip. Left the TR250 with its owner in Jacksonville, FL which 
has freed up one garage space.
