i converted my 07 nbs work truck from a 4.8 and 4l60E to a 6.2 and 6l80E. I want to go 4x4 but the transfercase I have doesn't have a long enough tailshaft. It has a yolk like the rear and does for the output. I'm wanting to know if the Denali borg warner AWD transfercase housing interchange with my borg warner (440103901). Also is there anyway to make the Denali transfer case selectable If not what should I do about a driveshaft. It's going to be 75 inches long with the 4x4 transfercase.
