Don't know if it was an option or not, but the aftermarket does make kits with everything for the window conversion, sorry, can't remember where I saw this, Im sure it was a street rod specialty shop of some sort. If I remember, the price really wasn't to bad, like $200 or so for both, which is why I remembered at all! I would think the same thing would be made for door locks. Might also check out some full-size Bronco's, some had a higher level of "trim" and might have had that as an option in the early years and could provide donor parts.
I've looked at many and have NEVER seen one! I know because I've been wanting some for a while, but they could have been an option.
JC Whitney and LCM truck has some kits for the $200 range, but I've always wondered what they install like. From the pictures, it's hard to tell if they replace the old regulator or if you keep the stub for the handle sticking out.
I'm thinking about getting a few motors from the junk yard and making my own setup, seems like the cheapest route.
