To get a driver drop front diff you can flip the axle housing, flip the knuckle balls, and weld on new spring perches. Then you need to install new drain plug, weld up the old vent, drill and install new vent.SO....I was hoping for more "info" on a swap than suggestions on other options. I have my other option, it's an LS with a 4l65 or 4l80 to stock toyota split case, done/tried/true.
Getting info about the Hughes Adapter (3.5 EB to GM transmission) was what I'm looking for. I think having the 6r80 would be far superior, it's an extremely tough transmission and is designed for the EB. Going to a GM 4 speed might ruin the benefits of the swap, but would elimnate the transfercase issue. I've spent hours digging through other EB swaps and have narrowed things down to really one single insurmountable hurdle. The transfer case (as mentioned in this discussion) is a passenger side drop on our vehicles, while on all Fords it is a drivers side drop. This hurdle is somewhat big. The 6r80 has a 31 spline output 6 bolt pattern and no-one makes an adapter .
First option, I found some people saying you can swap the internals from a Ford NP205 (drivers drop) into a Chevy NP205 (passenger drop). Retaining the 31 spline input and 6 bolt pattern, I do believe it would bolt up to the 6r80. Second option, literally clock a ford NP205 to the other side and drill/tap new drain/fill/vent holes. The NP205 uses a lube bath (sounds fun?) not a pump, so lubrication shouldn't be an issue. Adjusting shift linkages would be doable but a PITA. Third option would be to find a machine shop capable of either converting the 6r80 output shaft to 19 spline or visa versa with the Toyota case.
Anyone else know how to remedy this problem?
