My search continues for the right candidate for my 70-71 Ranchero. Looking at a bunch of different trucks I see that power windows are pretty rare. I would like to see if it is possible to retrofit a power regulator to make that happen. Guessing that original parts are either rare/pricey or not worth the trouble due to age. Almost every car built today has electric windows so the potential for parts is there. Anyone done a re-fit? Also, what do I need to delete a column mounted shifter? Seems that blank collar came on more than Rancheros and Torinos. Thanks in advance for your input.
