Darkside- from my lhs for $310. Not bad considering Tower is at $349!!
I forget if the front opening for the diff in the graphite/bulkhead is the same size as the rear? I remember hearing about putting a rear diff in front for $60?? Right now i'm enjoying the one-way though. I had to bump up nuetral on the radio so I would get more coasting and it works great for me- one-way didn't like the sudden motor stops
