My 67 ragtop was originally a 327 3 speed Standard but the previous owner installed a 1973 to. 1975 Saginaw 4 speed. However the speedometer does not work on the car. I removed the speedo cable from the tranny and the little plastic gear is missing from the end of the speedometer cable. Does any one by chance have a part number and or pics of this item. My main case number is 3925656 and the ext. housing number is 326558. I believe this to be a sag from 73/74. I am live in Canada and would like to pick up the gear so I can get the speedo working. Also is there a clip that holds this in the tranny or does it just slide in on the end of the cable. Thank you. Any help would be appreciated.
