Hello Mr Physics (sounds like a nickname for Einstein)
Since you plan on having the board touch the end bell, is there room for a second blank card to be squeezed in there? My experience with the typical card stock used for eyelets is that it is fairly flexible. This would give you security against any arcing and allow fuller use of the card.
Another notion comes to mind, where you turn a locking nut down each of the long bolts to use as a stop to apply a short spacer above, into which you can thread a short bolt once the board is in place.
We like to podge things together here - jolly fun! - saves money some time - saves time some time - but some times it looks quite odd after a while if you go back into the chassis to do something later. Then you wish you had done it cleaner, or more in a typical fashion that would not incur your own regret let alone comments from others. I recall Mr O'Connor saying in one of the books that it takes the same time to install a good quality component as to install a poor quality one. I believe that was with regard to quarter-inch jacks. In this case, it would be a comparison of improvisations; the long bolts could look a bit crude with so much exposed thread, where covering those threads with any kind of tubing may look nicer. The outer sleeve of coax cable comes to mind.
This is an aesthetics comment, I must admit, and every engineering solution has its own beauty.
Cheerio
