Does the Arctic Cat 500 share the front differential with the Vinson? The reason I'm asking is cause the AC diff has a diff. lock so I was wondering if there was a way to turn the vinson diff into one that locks. The old AC 300 could be made into a locker by playing with the linkage, cause it was the same as the King Quad that had the diff locker. Just curious if anyone has tried or heard anything about this?
