Alternator/Dynamo pulley

[browny]

Im changing the dynamo on my '71 for an alternator, I already have an alternator from another bus i broke but only half the pulley! Am I right in thinking the pulleys are different on a dynamo? I looked at Heritage and it doesn't seem to differentiate between the two. Any help or an alternator pulley would be much appreciated

Thanks

When i converted i used a chrome alternator pulley (it came with the alternator).
My Dynamo pulley fitted but was to deep so when i tightened it onto the alternator it bottom out on the casing and wedged itself.
The alternator 1 was a little bit shallower but i still needed to shim it away from the casing, i used some spare adjustment shims i had and (touch wood) i've not had any issues since.

Ok, so i definately need a different pulley then. I'll have to get searching! Thanks
