" From: "Armand Eshleman" <aje1@xxxxxxxxxxxxxxx> " " Hey everyone, " " I'm looking for a good set of used 2.73 ratio gears for the AMC model " 20 axle. I think this ratio only appeared in Jeeps. " I am putting this set up in my 70 Javelin. I have the twin grip differential " for the gear set. I think this ratio will be great with the T5 manual. " First gear in the T5 is very low, barely get rolling and I need to shift. " Also I like the option of being able to cruise in 4th or 5th gears. Fifth " would run the engine at a low an rpm. Great gas mileage. If I'm " not thinking correctly on this I hope you guys will let me know before I " get too far into it. what gear is your carrier from? the 2.73/2.56 gears have their own carrier separate from the 2.86-up gears. iirc 2.73s and 2.56s could be found on some late-'70s amc v8s. they can also be found, with torsen posis, in hummers. amc20 3.07s and 3.31s can only be found in jeeps. i still would like to know if the hummer 3.08 fits the regular hummer 2.73/2.56 torsen carrier or if it has its own carrier. i am assuming you know that the hummer [h1], true to its amgeneral roots, has amc20 differentials. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
