I am in the process of installing a gauge cluster for my 80 Malibu and I have two different round speedometers. One goes from 0 to 80 and the shift markers say P RNDL2L1 and the other goes from 5 to 85 and the shift markers say P RND21. Which one is the right one for the car? Personally, I am guessing the 0 to 80 because it came with a dash Im guessing was orginally from a 78 to 80 Malibu because it has no check engine light (hence no computer) but I just want to make sure. THANKS!

 

Well i will put in that i know my speedomter is exactlly 5 miles per hour faster than what the car actually does. It may be the same in your vehicle you never know. Just an idea.
