My speedometer quit working sometime this weekend in my 91 RS. I was wondering what all would have to be changed to install the 145?? Z28 Speedo in my RS. Direct bolt??

If nothing else, does anyone have a really cheap working RS unit Or even an extra Z unit if its a direct plug/swap.

 

I don't know if it's direct bolt for the 91 RS. You have an electrically driven speedometer, and it might need calibration! It was a direct bolt-in for my 85 IROC when I swapped my 85mph speedo for a 145mph one, but it's mechanically driven. Check out the archives here on the boards, or check the tech articles section! :P

it should be a direct swap.

Ok, so no calibration needed. What about the tach, I did some searching and some said tach was screwy afterwards. Just swap my rs tach into my z cluster and install?

 

i donno if its a direct swap, but i DO know that they use the exact same VSS...
