What years am I dealing with?

Tunnel says ss440A-003390
Motor says TC440A-A201
What part numbers would I use for the crank seals?

Looks like a 78' Invader.  For future reference you can find this info here:  http://kawasakitrax.com/models.htm

Crank seals can be had at newbreedparts.com or denniskirk.com

Thank you. It ran last year but not well.

You're on the right track, crank seals are a must.  I also recommend rebuilding the fuel pump, cleaning the carbs & fuel tank, and replacing the fuel lines, filter, and primer on any sled that this hasn't been done recently.

I completely agree!

This was cobbled together by last owner, it runs but has the typical issues I’ve read about.. so it’s definitely getting the basic must do’s.
I’m currently on Dennis Kirk looking, trying to get an idea of what it’s going to cost.
I need to rebuild both carbs and re-line everything. If anyone can give me part numbers it would be a huge help. I’m not to handy with this smart phone.
Carb rebuild kits? And what size lines are used originally?

You probably won't find a rebuild "kit" for the carbs.  As far as everything else you need, I suggest calling newbreedparts, they are a smaller company that are intimately familiar with these sleds.  They will be able to help you and give you fair pricing.
