Wow! That's a great batch of information!
Ok, well I will see what happens when the parts finally arrive. I have new doors on the truck and they seem to be correct for 1977 on up. The door panels I ordered are also for this era so they will fit and work perfectly with my regulators etc. I might have to settle for the 77 door handles but it really looks like the offsets etc are in the same direction as the early versions as compared to the mounting holes etc. But I trust you more than me on this as I'm green to the whole deal. If I can at least eliminate the crappy 1977 window crank handle it will be a good start. ;-)
Thank you so much for the information.
