List,

A couple of comments on the Bosch (Ford Fiesta) alternator:

1. The TR250's adjusment bracket interfered with the alternator fan and had 
to be subjected to modification by the bench grinder.
2. The clamping bolt required, of course, was metric. Another trip to the 
local FLAPS is you don't have one lying around.
3. The pulley width is most suitable for a 1/2" belt as used on later TR6s. 
The TR250 and early sixes use a 3/8" wide belt. I used a 3/8" wide belt 
which worked out O.K. The alternator didn't seem to mind the slight increase 
in speed and the belt did not rest in the bottom of the groove.
4. I never did find a proper single connector, with or without a pigtail, so 
used 3 individual lugs from my Lucas stuff. The 3/8" female connector is the 
hardest to find. No local auto parts store or Radio Shack had one.
5. My "first ride" was from Pittsburgh to Savannah, over 700 miles, with 
rain requiring headlamps and wiper in South Carolina, so I'm glad I did the 
conversion.
