Changing rear end gears

Hi everyone,

New here....I owned a 1978 approx. 15 years ago but ended up selling to a friend. Have always regretted it and now looking to replace it with something near the same age. Actually, would love to get a C2....but you can't always get what you want....and still love the C3's.

I am looking into buying a 1981 with four speed but want to change the gears in the rear end. Seems someone changed the OEM to a more aggressive ratio and the car runs extremely high RPMs on the highway. I would like to return it to a more stock ratio.

Is this a major job? Costly? I might be willing to tackle it myself with some help from friends....but may just have to take it to a mechanic.

Before you go down that route have you considered putting in a 5 speed transmission? Sure it will be more expensive but the end result will be better you could easily cut 500 RPM off your highway rpms this way and still have the low gears for off the mark acceleration which wouldn't hurt if you have a stock motor.
