axle swap

So I have my bike taken apart right now I just found out it’s a 2002 from 88 blaster , and I took the swing arm off and rear axle off as well the axle didn’t want to come apart so now I’m replacing the whole thing .. this is my question I took it apart because I need a wider axle and a longer...

I searched and searched for a thread about rear hub/axle swaps on the later model blasters. Surprisingly i wasn't able to find one. Maybe yall know something i don't (Probably the case). I can not for the life of me find /dirt/trail rear tires that fit the stock 8" wheel. Are there any 9" wheels...
