what do you have to do to make a 145mph cluster work in a 110 mph car?

------------------
'92 Z28,t-top,PPG jet black,5.0L TPI,Auto w/stage 2 sft. kit,
michelin pilot 245/50/ZR16 tires,polished plenum/intake,flow tech 3" exhaust,PIAA driving lights,2 kicker 10" comp vr subs,jl audio componet set in q form kick panels,kicker ix405d 5 chanel amp,pioneer deh-p735 deck

 

nothing, the speedometer is calibrated at the transmission, it should just slide right in the dash.

 

yup, thats all you gotta do man.

 

Just remember you need a speedo from a 90-92 car.
