Speedo Gear for Tranny

[slepr1]

Anyone know where I can purchase a speedometer gear for 4:30 gears for a 727 tranny?

Well, the good news is that Mopar still sells speedo gears. The only thing you need to do is to match the tire height on the chart to your tires. There is a site on The Mopar Web Ring (I forgot the address-maybe someone else has it) that has a list of all the speedo gears by PN and shows which one goes with which tire size & gear ratio. If you don't know the exact tire size you can go to Randy's Ring & Pinion site (ring-pinion.com) they have a tire size calculator. Having said all this, I bought a new gear based on the web site's recommendation for my tire size & gear ratio, and it made no freaking difference! I don't know what I did wrong Maybe someone could explain this.
