" From: Marty Bricker <mbrickerusn@xxxxxxxxx> " " I changed the rear end of my 74 Jav from a 2.87 to a " 3.54 and my speedo is now showing much faster than " actual. " [] " Is there a way to determine what speedometer gear I " need to order for my 998 tranny (I assume the MOPAR " guys would not be much help on figuring it out but " they probably carry the gear) frank covered it pretty completely. i'll just add that nobody should need more than your tire size and axle gear - and maybe tranny speedo drive gear, if there's more than one as in stick trannies - to figure which speedo driven gear you need. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
