Ski doo snowmobile question

Hopefully someone here can awnser a technical question for me.

I have a 91 skidoo formula mx. The fuel tank grommet is so far gone I can't even pull critical measurements off it and I'm trying to source a new one.
Online I havnt been able to even find part numbers past 1995 and nothing for the MX. The nearest ski doo dealer is an outfit I refuse to do business with.

Befor I start buying random pieces of rubber untill I find one that fits, can someone tell me what if any crossover there is on fuel tank parts between years and models.

Bubber have you tried Partzilla. OEM parts for pretty much everything. Eric

Partszilla only goes back to 1996 if I remember correctly, on my old sleds I try to find similar material and make my own

I can’t help with your questions - just wanted to say HI. How you been?? I miss seeing you and your Dad at Prineville.

Hope you’re staying busy and safe!!!

Dang that is a new thing for skidoo parts to only go back to 96. Been a while since I had one that old to buy parts for.

Dennis Kirk maybe?

Wish miss
Nancy, it's good to see you. My dad is well and I'm still kicking along with 2 little ones.

Yep, this is what I've come up with too. This sled is the worst free thing I've ever been given.
I'm giving this one last effort and it's getting fixed my may, untill it runs and I'm selling it.

Somebody explained to me why most of the supply places only reference back to '95. But if you keep looking around you will find one or two that go back farther.
