Does Ford still use spedometer gears?
This is for my wifes '01 Marquis, so bear with me. I spotted a complete rear axle assembly at a swap meet out of a Police car. It has 3.55 gears and a traction loc.Our car has a 2.73 open.Can I swap this into the Merc without causing havoc? I was under the impression that the speedo was electronic, but I'm not sure and she's got the car so I can't check it out.
I'm trying to get as much info about this before I spring this on her ."but honey, it's good for driving in the winter" Wink,wink.
