Hi all, first here are the specs.
Daily driver '72 Dodge Dart Swinger, 318 5.2L LA with A904 automatic Torqueflite tranny, 7 1/4 rear axle.
Tires are Hankook P185/75 14 with 25" diameter.
My questions are (and please excuse my ignorance on this):
A- Is the axle ratio for the transmission 2.76:1? If not, how can I find out what it is?
B- Is the speedometer pinion 28 or 29 tooth for that tire diameter (provided it's a 2.76:1)?
C- When I remove the original speedometer adapter and pinion, will I be met with a large amount of tranny fluid rushing out? In other words, will I need drain the pan b4 removing the adapter and pinion.
Your expertise is greatly appreciated.
