Hey guys i have a few questions on a sled that we are going to be building soon. Its a 2003 600 ho, with the beavertail on the back, he has the old skid out of his 07 summit 800, which is a 144 and a 144x16 track. Now my question is wil this suspension bolt rite up into the 03 chassis or do you have to do any mods to the suspension or chassis, also what kind of tunnel extention would you recomend? Any help on this is well appreciated!
