This is Troy, Mikes co-driver. You can contact Mike at 916-257-5563 or firstname.lastname@example.org. I'm not sure about the 2wd trans. We pulled the trans last week and the new Kragen Yerington special clutch came apart causing our dnf. We are currently waiting for a new clutch, having the flywheel lightened and taking some of the transfercase/front wheel drive stuff out of the trans. Thanks.
