John,
When it comes to mistakes, I am King. You might need a lifetime to de-throne me. Just on this topic I have made, at least, three mistakes. First (as I've already confessed) I said the studs would hold down the head-steady brackets - WRONG!, those are bolts. Second (and this I just noticed from my first post), I brain glitched and said the 18 TPI Whitworth goes in the cylinder instead of the rockerbox. Third, I said I thought it would not be possible to use cap screws in place of studs, and Rocket Racer has done just that. GAWD! I hope there aren't more mistakes in this very paragraph, I might never catch up.
John,
Still confused on the front cap screws. Do you mean that you drop them into the holes in the head fins before you put the rockerbox on or that they can actually be sneaked in after the fact?
