Yep, just what I need to go to work, haha!
Neat stuff guys! I'll find the full build sheet on that Cutlass. I see he used a 4l80 trans but doesnt mention what t-case. Regardless, he must have clearanced the floor a lot. Not a big deal as long as that case lands under the seat where the custom floor pan can be raised without affecting foot wells for the case and front drive line. Regardless, I would run few inches taller than the Cutlass's stance which should help for drive train clearance.
Read that he used the front and rear diffs out of a ZR2 S-10 truck and aftermarket shafts. So like some of you said, this is Typhoon and Cyclone drivetrain thus im betting the t-case too. Good call!
