I am wondering if both of the w123 and w124 wagons cargo covers can be installed in any wagon. I do know that the w123 wagons which came without the third rear facing seat have all the proper manufacturing features to install a third seat- so all you need is the third seat and it's related parts.
Is this also true with the cargo covers? I know the back of the drivers side in the w124 holds the cargo cover mounting hardware on wagons optioned that way from MB. Are
all wagons able to have the mounting hardware installed (meaning wagons not sold with the expensive cargo cover option)? IE is there the two areas on the drivers back seat which allow the mounting hardware on non optioned versions? It would be a rectangular cut out and threaded receivers for the bolts which hold the hardware.
Sorry I have no pictures.
