Hello. I got a 77 X's 360 my front forks are shot. The stanchions are badly pitted I know they are 33 mm. My question is I found some off a 81 X's 400 special I think they should work it's still a sohc the dohc motors got the 35 mm forks also would the length be the same or were they different. Sorry if it's been asked before I did try to search thanks again
