1990 Dakota 2.5/ 5spd manual A535/NP2500 gear ratio ?

Yeah, but providing replacing the trans tunnel for fitment, the NV-3500 is a lot more "340/360 friendly", lol! Talk about having to "feather the throttle" out of the hole in first though, even with the 3.49:1 ratio. Let's say 3.73 gears, 13.02, 8.06, 5.22, 3.73, 2.73. Here is a pic of a transmission fit for a C-body wagon. NV3500
