No sir that's the right part number

[neverfinished]

Well this morning was fun. I got my new window regulator yesterday and set aside time to install it this morning. I figured it would be about an hour job mostly pulling everything off the door then gliding the old regulator out and the new one in. I was wrong. I got the door stripped down and started unbolting the regulator. My plan was to get the regulator loose then slide everything to the side to get the rollers out of the window rail. As I pulled the third screw out of the regulator, it very quickly turned 90 degrees pulling the bottom roller out of the door and wedging itself between the inner door and the front window support. I tried to roll the regulator open or closed to see if the arms would bring it back to center but I found out exactly why the regulator was acting up in the first place. The two sets of gears weren't engaging so when I pulled the third screw all the tension on the spring let go and everything pivoted around that last screw. I started trying to work the regulator out of the door squeezing the arms together the best that I could and trying every angle imaginable to get it out of the door. 45 minutes later I had it out laying next to the new regulator. Something didn't look right, I checked the tag on the bag that the regulator came in then checked my receipt then made a phone call which pretty much ended with "No sir that's the right part number, we don't have anything else listed for a '73". The rollers on the new regulator were noticeably larger than the ones on the old unit. Just to see if maybe it did fit I slid the new regulator in (much easier than getting the broken one out) and tried fitting the rollers into the window frame. Nope, they were too big. So I tried the roller on the door, that's weird it fit. I pulled everything out again and went to work. One grinder, a couple of nuts and bolts and 20 minutes later the new regulator had two smaller rollers installed. I tested it a few times before I put it in the truck to make sure the nuts weren't going to bind on anything then went to work putting the new regulator in. It took a whole 5 minutes or so to put the rollers into the frames and bolt the regulator in. Why couldn't the whole process have been this easy. I got out the grease gun, made a mess inside the door, tested the window a few more times then put everything back together. Just a warning to those with broken regulators, be ready for the spring to let go on you when you're taking it out, my heart skipped a beat and either I have newer window frames or the regulator I bought isn't exactly a bolt in replacement.
