I sprayed liquid Wrench on the speedo needle bushings and got them working smoothly, turning the unit with my cordless drill. Then I sprayed the same bushings with Fluid Film, and believe it or not, that was too thick of lubricant. The needle started sticking again in odd places, going up and coming down. So I had to clean the thick stuff out with more weasel-pi$$, and it got working better again. The first picture is my drill in second gear reverse and the needle goes smoothly back and forth. Third gear is almost a hundred; whoooa, what a rush! The second picture is the speedo back in the dash. It took a few tries.
I have been sanding and repriming my mock power-steering cap, until I got bored so I painted it.
