It would not work. No way to get the dimensions precise enough. Unfortunately, you only have one option that I know of and that is to have the tubes rechromed by a suspension shop. I believe only a couple of places in the US even offer this service--basically all the shops send their stuff to the same place, and it will not be cheap. I would look at a salvage yard--any 46 mm tube from a yamaha or kawasaki, etc. should work, I would think.
