Slick 60's

Is thereasimole way of reinstalling wiper arms on a 66F100? And the dash knobs and trim pieces....should I buff those and clean the knobs or just buy new ones? Any suggestions are greatly appreciated.

Wiper arms are simple as long as the mechanism under the dash is already there. Just make sure the motor is in the parked position and push the end over the nub close to the bottom of the windshield. Knobs are available new as are the white inserts. Depends on whether money or time is more important as to replacing or re-using.

Knobs clean up nice with a spray bottle of cleaning solution like simple green ect. and a toothbrush. New white inserts from Denise Carpenter are available. I used coat buttons from a fabric store. Buttons come in a variety of colors and metalic finishes. Folks have used marbles and coins as well
Good Luck and Welcome
