i was just curious how is a guy to know exactly if he has the 827 (was told i do by the seller) or not? i do have the gold head im assuming its 14.5/1 ? and also is there a re ring kit the sled runs fine i just think she could use a little more life before a final trip out west this march. whole list off mods including d/r seat mod what foam should i use? and do i have to roll skid back or just down? thanks in advance!
