I'm trying to swap an 1991 e350 Engine and tranny into a 1994 IDI turbo f-350. They sit in the truck but my shift cable from the 94 won't match the shifter on 91 transmission. Is there an adapter? Mod? I've failed four different mods... and I still have the 1994 Tranny, but hate having to pull the tranny to swap (alone). Just a side note... you can install engine and tranny at once... load leveler helps.
