Hey all, can anyone tell me what the difference is between the 66-67 striker posts and the 68-77. I have two marked 66-67 and I need them for a 66 but the holes for the striker seem to low and mine were so rusted that I have nothing to compare them to. I believe these were mismarked and would like to modify them to work but not sure how much higher the holes for the striker need to go. Any help would be appreciated thanks.?:?
