1966 Plymouth Valiant front door arm rests

I do not, but the bases are easy to find, think most new ones are chrome but that would look nice unless you still wanted to paint them. The originals are fragile, not sure how strong the new ones are. And yes, the pads screw to them. My 66 Valiant 100 has the short bases, they are the same length as the rear ones in the Barracuda...Barracuda had 2 sizes. On your car...are the front the same size as the rear?

I measured them today and it looks like the fronts are 9 1/2 " and the back s are 10". I dont know if that is supposed to be right. I think I saw somewhere that they should be 9 & 11"
