I replaced mine last year on a 92 Legend 43. I took the old takn out and sent photos to 3M (?) to fabricate a new "plastic" one. After all was said and done, I should have measured the space where the tank was housed and I could have bought a tank "off the shelf" that would have worked just as well and a lot cheaper. I found getting tot hte tank quite easy as I only had to unscrew and remove some furniture and floor boards. Good luck
