I am very surprised particularly that the sheet metal under the trunk floor is different. I was looking specifically for the area under and around the spare tire. Would that smaller area work?
All other 124's had a spare tire well designed for a 6.5" to 7.0" wide wheel. The 036 had 8.0" wheels, and the sheet metal around the spare tire had to be deeper to accommodate this. I'm not positive if the diameter is larger as well - I don't think so, but I've never measured it.
If only the very bottom is what you need, it MIGHT be possible to cut that out and weld in the .034 section, assuming you cut a couple of inches up the wall, and the shape/diameter matches exactly. I've never researched this, and don't know anyone who has attempted it.
In general, the only reason you'd need to replace the bottom of the spare tire well is if a hole rusted through. And in that case, smaller patch pieces will suffice as a repair, unless the entire base is rotted out (which would be
very unusual). Years ago,I had a body shop repair a couple of holes in the bottom of a 124 spare tire well using patch pieces from a donor car, instead of cutting out the entire tire well.
Dave, I have just signed up for the EPC. Despite being quite a bit more technical than the average individual, I find it utterly unintuitive, even having read through (quickly) the badly written and overly technical manual/guide pdf. It's the kind of user interface you might find in the earliest iterations of any form of GUI. Pathetic, really. I shouldn't, as an average user, have to deal with this level of unnecessary complication. See my post here on the subject:
Heh. You think the EPC is bad, you should try the WIS! The WIS is next-level misery. The EPC gets easier as you learn the quirks. The WIS remains torturous to use. Remember, Mercedes never, ever intended vehicle owners to use the EPC or WIS. Both programs were designed for Mercedes employees who would be factory trained on using both.
Anyway - the more you use the EPC, the easier it will get. For the 124 chassis you don't necessarily need to enter your VIN each time, just the chassis code (124036) will suffice. On newer MB's you really must use the full VIN, as it will automatically filter out results that don't apply to your specific vehicle. There's no simple reference on how to find things, as you spend more time looking, eventually you'll remember what group certain items are located in. Even now after 20 years of using the EPC, sometimes it takes me 10-15 mins to figure out where MB put some oddball part.
