in a 1 ton I would go with the 4500 its cast iron and heavier built than a 3500, do you want to run a hyd clutch ?? if not you can change the front bearing retainer and run a mech clutch, installation is easy depending on what year the tranny is early years use the same bell housing as your sm465. and if you have a later year tranny you can get the bellhousing from several diff places I like the adv. adpt. as far as the shifter location its about 3 to 4 inches straight back from your sm465. you will basicly have exactly what you have now BUT with a overdrive. tho first (granny) is not quite as low
the 3500 has a intergrated bell housing and you would HAVE to use a hyd. clutch and its not near as strong, hope this helps Coop
