\'73 K5 window regulator swaps? My drivers side regulator stripped the gear today. /forums/images/graemlins/mad.gif I knew it was on it's way out when I got the K5, so I've been loking around at yards for one in decent shape. In the LMC catalog, they list a part number for 1973, a different number for 74-76, and ANOTHER number for 77-91. When I've found a decent one at the junkyard(JY generally has '77-'85 or so Chevy trucks) it looks like the splined stud that the handle mounts on is longer than the one currently in my blazer. Does this mean I need to find a 73-specific regulator?
