Well......well .........well. .............f iddlesticks. I found out that the stock Duraspark distributor will not fit because of the idler pulley directly in front of where the vacuum advance canister would fit. So, I will have to use one without vacuum advance. No biggie, as it was probably a moot point anyway since the camshaft is fairly stout. Probably wouldn't have a lot of part throttle vacuum anyway. I will just get a performance magnetic pickup style distributor with no vacuum advance and a black cap and use the Duraspark connectors to wire it to my fake Duraspark box. lol
