how hard is it to swap a 85 mph to a 140 speedo?

Its just a matter of taking apart the dash, taking off the 85 mph and puttin the 140 mph and putting it back together. Make sure and get the correctspeedo tho, they changed when the airbags were put in.


Thats what it will look like all torn apart.

Yea, it'll read right I think. I dunno for sure because mine hasn't read right since I changed my rear gears.

yes it is

as long as you get one from a air bag car and you take the hole speedo gauge, not just the face. it will read right if you take the gears behind the face that the cable goes in to. I did the same thing to mine. except mine has no airbag.
