Hi Em,
That paint sample is a finger dab and as such will always react differently to spraying. I don't feel there's too much of an issue there.
Did you get them to write the formula down for you ?
As far as the roller shaft is concerned the end piece could be easily reformed back to what it used to be prior to its constant bashing that its had over the years. The main thing to concern yourself with is the wear on the shaft itself where the plastic caps have been rotating on. The shafts as replacement parts are quite pricey but really all you have to do is cut the shaft off at the anti rotation flange, then drill it out and replace the shaft with a new piece and re-weld along with running a die over the end to cut a new thread.
In regards to the handle bars, they look magnificent, I'll swap mine for yours,
Cheers,
BB.
