You can't put the 140 face on a 85mph speedo mechcanism, you have to get a 140mph unit(take the whole thing apart and switch the whole mech that the speedo cable hooks into). I'm not very happy with mine as after getting the 140 mech. $75 on e-bay,
& changing it all out my backlighting looked like crap, could'nd read all the numbers at night & the yellow on the tach was blinding. So I took it all out agian and after cutting off some misplaced plastic light directers and swapping brighter bulbs in some spots & dimmer ones in others it is a lot better but still is pretty crappy. A lot of hassle IMO.
