im not sure whats going on with it but it will read about 15-20 mph when im actualy doing about 60-70 mph does anyone know what could be going on the only thing that i have done around the guages is the needle fell off and i glued it back on could that be why? if not what could it be? thanks

 

also could it be that it isnt the correct speedometer for the car? it is a 115 mph speedo the car is a 88 camaro the dash says its a z28 but the side badges on the ground effects say its an rs the kid i bought it from told me the side ground effects were replaced because they were broke so im not sure if it should have a 115 speedo or possibly its supposed to have a 145?

 

Yes.

A 145 will swap in if you should so choose.

will one swap in with no other modifications?

which one of those in your post would be the most likely for my problem?
thanks

 

No other modifications are necessary. To avoid any possible electrical gremlins, I swap in the speedo head only.

Hard to say.

as in un bolt it from the plastic cluster and replace?

 

Yes. The following link will provide a bit of a how-to:

ok cool thanks im going to try to find a 145 speedo if i cant i guess ill have to settle for a 110 do you know of any? i dont have too much money to spend as i am a full time highschool student

 

I have a 145 speedo head (not the cluster) that was refurbished at a GM facility ($80), but in my car it always jumped three or four miles an hour starting around 60. Should you be interested, I'd take $25 shipped. If not, you might consider advertising for either the 145 or the 110 in the site's classifieds.
