Oh, I hate it when I do that (!) Which pulley is broken, and how badly? Right before I sent off my piece with a chunk missing to have duplicated by JK Pulley, big brother suggested Harley the brilliant welder at ACD and now I have a genuinely round original. I had a NOS front pulley someone bought thru Ebay ~9 years ago, but wherever there may be a spare has still escaped.
(and PS, after breaking the cast yoke on the clutch linkage while removing the tired clutch master cylinder on 8ma1046, I was super, super careful when doing the same thing on 8ma1076...and well, broke that too. At least, second time making a steel bracket was easier !).
