I love that maintenance parts are still so cheap for the W114, I swear I think they are cheaper than W123 stuff.
That's comforting I'm not alone in my thinking. This all started when i won a pair of re-man front calipers cheap on e-bay, seeing as mine were miss-matched. I bought rotors since there was a little evidence of shimmy the last few months I was driving it this winter, then noticed the setup with the rotor bolted to the hub, so I ordered bearings (SKF) since they were cheap.
Lot of labor to change all that stuff, it's a solid way to build it though. Very interesting. I used Textar pads which are Mercedes stock but minus the logo and half the price.
