I'm loading up parts for the Nationals and I'll looking at a boxes of pullys. I know first hand how frustrating it is to have them mixed up and the belts not line up perfectly. I've got several sets but over the years I've just put them in boxes without stringing the sets together. I thought I'd remember where different parts came from, but that didn't work out I'd like to offer these up for sale in Reno but want to make sure I'm not selling someone a set that won't work for them. Anybody who has time, please look for the letter codes on your pullys and let me know which codes match each other. Almost everything in my driveway has been monkeyed with, so they don't have the original combinations on the engines anymore. John
