I had a quick look on ebay this morning and didn't see much in terms of used, but I'll keep looking. If I change one pulley and or bracket I have a feeling I will need to change them all.
I think I need at least the crank pulley, water pump pulley, PS bracket, and Alternator braket. That would allow me to use the old alternator with the skinny belt and the 350 PS pump in the BB bracket, right?
I have to get it running and out of the craft center today to avoid extra charges, but if I can drive it five minutes back to the house I should be allowed to do a little work there.
