Sounds reasonable - with all those things lined up in your favor, you'd definitely have a fighting chance of making it in a weekend.
im confident i could do it in a weekend, but im not confident this transmission is very strong, and the tcase is also questionable, so if i find a good r1 and 1354? or is the electric one 1350... i forget. but ya with the electric t-case attached i would attempt it. not til i have a DD in place tho, just in case.
all i know is that a decent hardware selection and numerous drill bits can make a 2day job a 2 hour job. or vise versa.
