Coolant Overflow Tank Parts - Futile Effort?

Just got my 86 700 about a month ago and you guys have been super helpful in my resto so far. To introduce myself, Im Jeff, 22 yrs old, was into Honda quads since age 9, racing, wrenching etc. Just got into my first Street bike and I feel like I've been reborn : ) But anyway, I have a dry-rotted and cracked Coolant Overflow Tank stem. Whenever my bike utilizes the coolant overflow tube when heated up, I end up with hot coolant on my legs and feet, and constantly filling my overflow tank. Ive tried to find a replacement at local Honda dealers, online, etc but no luck. Honda stopped making it and no other companies in my searching make it either. I did replace the overflow tube, and in the process, cracked the nipple on top of the overflow tank, and cracked the rubber gasket in half. Was considering a silicone, rubber cement fix, but would rather do it the right way. Anyone have any input on this?

 

Dozens, hundreds, thousands of these parts are weathering away in salvage yards coast-to-coast, so try there.

 

I spy with my little eye a RWB tank in that pic.

Can you?

 

LOL!!! The irony is thick. If a center stand can be found for a gen 2 I think an over flow tank should be easy.

I kinda was looking for a brand new one as not to incurr the same problem ive had with this one - being old as dirt and dryrotting out. Guess im gonna end up resorting to the silicon/rubber cement route...
