Speedo gear

[Sparky]

Does anybody have the part number or any info on speedo gears? I am so tired of trying to figure out how fast I am going. I went from 323 to 355s so things are out of wack, mind you they were with the old gears also but only by a few MPH. The car is auto, 14 inch wheels, probably need tire size also? I think? I will have to go double check that. What else is required to figure out witch is the correct gear?
Thanks

Try www.moparts.com. Go to the tech archives. They have a nice
chart for getting the right gear. I saved it for future referance
I was changing gears like crazy. It came in handy.
