Hi Vic,
Yes, I used Ford 1971-73 rubber door jamb boots. They have plenty of space to run wires, they look stock if that matters, and they fit in the stock door jamb and kick panel positions on a 1969-70. The factory grommet hole sizes are larger on a 69-70 than the 71-73. If you have the luxury of drilling fresh holes, than the kick panel hole is 1 1/4" and the door jamb hole is 1 5/8". You can use the factory dimples if you have them. IF you are retrofitting them into a door that already has factory holes, then I suggest cutting off the grommets from the 69-70 harness and inserting the 71-73 boot ends into each of the 69-70 factory grommets or inserting them into another grommet of similar size. I had a factory door and a repro door, so unfortunately I had to do one of each. Inserting the boot ends into the factory grommets worked well, but just for added assurance, I used some black 3m rubber weather-strip glue to make certain they stayed together.
They are many to choose from on eBay. Here is a set of 1987 Ford boots that look to be the same as the 71-73 boots.. https://www.ebay.com/itm/325160428669?hash=item4bb512647d:g:n0EAAOSwwp1iZDXr
Then again you could find a set of aftermarket boots.
