I'd think you would face about the same problems as I did, which were pan clearance, starter clearance, exhaust header on the driver's side, and transmission tunnel clearance. Assuming your vehicle is about the same underneath as mine, you will need to widen the transmission tunnel for about 14" back about 2 1/2". I have a description of my conversion at http://www.freewebs.com/rwooldridge/mercedes.htm
