Last time I checked it was cheaper to get the whole distributor. I tried to buy just the advance pot and it was with in $10.00 of a complete rebuilt distributor, if I recall correctly. I think the rebuilt distributor is around $50.00. I may have just the Vac advance pot used if you are stuck, but try a rebuilt if you can ;)
