yea get the grinder out and grind the heads off why try and kill your self with tools, easier just to buy all new bots anyways, they have all kinds of bushing at the hardware store to, should be no problem, if i only had a nickel for all the time I had the steel ,aluminum problem, seems like every snowmobile you work on has these headaches, im pretty such the arctic cats ive done before had the back bolt threaed into the bracket so you had to re tap everything, lots of extra work, why didnt they use antiseize back then
?? thanks
