'98 snopro gas tank?

I'm working on a '98 snopro and I'm having a problem with the "clear" tanks. They are crumbling with age,weather. We have got two tanks for this sled and they are both junk.
Is there a better tank available? Is there a black one that will fit?
Should we just spend the $$ for a new one?

Thanks for all the replys guys!
I went over to SleddersVision and they helped me.
Anyone here with a similar question, All the "Z" chassis tanks will fit, they can be cut down to fit the same as the original Sno Pro "clear" tank.
You can also use the whole tank and seat, It just has to be ETT or not.
