This morning I went down to the Harley shop. They have beautifull stainless steel "peep" mirrors that would work for my application. The end of the arm is tapped for a 1/4-20 thread. I thought-hmmmmmm----I could make up a rectangular plate with a countersunk hole in the center, attach it to the end of the post with a flat head capscrew, then drill a hole in each end of the plate and countersink them from the opposite side, to make an attachment base similar to the solid model. Then I asked the price!!!! They were $90 each plus 7% retail sales tax, plus 7% goods and services tax. Then I left the Harley shop.----I will whittle the damn things out of pine before I pay over $200 for a pair of rear view mirrors.
