Damn,, looks good! Great job. I think I may try that tank assembly for a 54 Cushman Allstate I have. I have a lawnmower tank strapped on it now, but it works and rides good too.
I had thought of the sealant between the wheel halfs of my FL250 too. I was just to lazy to clean them when they had to come apart again.
I will try and take some pictures today, then I'll figure how to post them.
