Hi,

I have a 1968 W110 200D and that has a 73 W108 280SEL 4.5 rear axle in it. I'm having a hard time finding rear calipers for it. I found the right and left calipers on ebay (different brands and prices)

Mercedes 190 280 300 450 560 Left Rear Disc Brake Caliper | eBay

Cardone Industries 19 164 Rear Right Rebuilt Caliper with Hardware | eBay

Not sure if these are the right ones. Were there any year to year changes for the 4.5, specifically from 1972 to 1973?

Thanks for the help!
