I have a Mack E6 motor with a Mack 6 Speed 2 stick transmission. I am going to pull off the Mack transmission an replace it with a Fuller 7 speed transmission that came off a Mack E7 motor.
I know the bolt holes line up but will it fit the input shaft on the transmission and is the bell housing the same length or anything else . The E6 motor had a 14” clutch and the E7 had a 15” clutch ?
Mack E7 and fuller trans fit Mack E6 ?
