Sweet front Bumper - let me know when you get the back one on.

And as for the seats I kept the original frames and just got new pads. Back seat pads /frames seem same between early and late w115s. Never tried the pre 74' front seats/pads to see if they fit.

for the front lower pads I used w123 pads from a junkyard for the seat bottoms (fronts worked perfect, the lower back pad from a w123 will also fit - the side edges needed to be trimmed, and it seems a little higher). For front uppers, Gahh sold me some a few years ago, they were marked with a w116 part #. They fit, but took a little trimming and wrk - maybe they have better w115 pads now.
