I could try using a piece of box tubing with braces welded to the ends, long enough to sit on the unibody 'frame' rails running along the sides, a triangulated set-up similar to the pictured tool.....but it would sure be great to understand how the Mercedes 'engine carrying stirrup' works (part no 107 589 023 61 00, pictured on page/section 33.1-110/2 of the 107 service manual)
