Well thanks for the replys

but got her done anyway. Bellypan hole were close but had to drill couple holes nothing major that was actually the easy part

. But everything swapped over very good had to change the handle bar mount bar and the oil tank hold that rivits into the chassis but otherwise everything was the same or close to it.
But i do have one more question this track when i installed it i see the there isnt much clearence between the track and the rail exchangers (like maybe a cm if that ) and it has studs. the chassis i took this track and skid out of was pretty chewed up from the studs honestly dont know how front heat exchanger wasnt leaking. But is this clearence cap normal? Seems pretty tight to me. Not sure on lug size ill have to measure but would hate to get it out and rip a hole on the exchanger ....

these are my first polaris sleds so gots questions lol heres before and after pic
