FYI, you can install a driver’s side regulator on the passenger side and vice versa, with a couple of issues. One, the crank will be at the bottom so it’s lower. Might not be an issue as the crank is now below where my left knee wants to rest, lol. Two, the window will only close down to within about an inch of fully open. Otherwise, it works. I have a passenger regulator on my 65 FJ40 driver’s side because the original and one aftermarket regulator failed completely. So I have an aftermarket one on the passenger side and the original passenger on the driver’s side. I didn’t want to buy another aftermarket because it only lasted a couple of years - passenger side gets used much less. Hence why I was interested in your sale.
