Well, I may have duals sooner than anticipated
Going to need:
Passenger drop waggy d44 housing
w59-gear case adapter
23 spline input
crawl box
mc-07 23 spline adapter
23 spline 4.7s (may order soon)
and another gear driven case
Once I get that crap I will just put all the stuff from my driver drop housing onto the pass drop and then put in the gear driven cases. Once I do that I will sell the tacoma case, tacoma case FROR crossmember and the driver drop housing. Should end up saving me a few hundred dollars.
I could even just get the pass drop housing in, get the w59 adapter and put some 4.7s into a gear driven case and just rock a single case until I can afford the other 8-900 to dual em up.
