Rebuilt my civilian distributor today. The tag says IAT-4416 which is the proper one. The problem is the NAPA AL128 cap does not fit. That is the cap number I see here on the zone and also on the NAPA parts list for that distributor. I am wondering if someone changed the way the cap is attached on my distributor. It has two "snap" catches about 1" long on opposite sides. No way the AL128 will snap fast which has the snap flanges right at the base, 3/4" short. Anyone have pictures of the civilian distributor that shows the cap attachments?
