Nice work! Great looking mod to a Z62. I think DrafterDan was looking at something like this last year? Maybe the year before? Man time flies! I bet a 16mm x 8mm silicone boot would be just about right to seal it up since the stock Z62 boot might be a tad bit long in your mod. And it might tail stand? Don't lose that Z62 boot. Most folks don't know that its also used on the SW02 and the Z48/49 tailcaps. And there is NOTHING available aftermarket if you ever need one.
Thanks M4! This will be going back to the owner along with the leftover parts.
