There's a shop called Dan's Driveline (702-658-5650) here in Vegas that will be doing the FrankenBenz's driveshaft. The problem is not cutting and welding the MB shaft, it's balancing it.

They weren't sure that they could balance my 2-piece MB driveshaft but (here's the important part), they know a driveshaft company in Los Angeles that can balance an MB driveshaft.

Give them a call to see what they can do or give you the number for the LA shop.
