I found a 500sel speedo, but, still looking for a 2.47 differential. Any one know where I can find one at a resonable price? I just don't have a lot of time to spend from junk yard to junk yard, soccer season as started once again.

So, will a 2.47 non-locker from a 420SEL (W126) fit a W123? My 300SDL (a 2.88) has a weird appendage on the subframe (for anti-torque I guess) and the diffy cover is not the same as a W123 either but I think that a regular W123 diffy cover will fit the pumpkin and thus make it useable on a W123.


Answer: This diff will not fit the W-123.

Went on a 1500 mile ski trip last weekend and the car did great. The first two tanks were done against a stiff headwind and yielded just under 25mpg at 80-90mph cruise (mostly 90). The return trip tank came back with 27.4mpg and my average speed was close to 90mph for 500 miles.

There's a 12 mile, 3000 ft climb to the ski area and I had to pull the shift lever to the bottom position a few times to get a downshift to first gear on the slow switchbacks. I had to manually shift to the next gear for upshifts.

So now that you have some mileage with the new diff how did it compare performance wise and mileage wise against the old one? Although I would not see myself driving my 300sd at 90 with the original gears.

Just for noise reduction alone the 2.47 is worth it and I would not go back to a 3.07 in a hundred years. I think performance is about the same and mileage is 2mpg better though it is a little early to say fer sure. The 500SEL speedo I bought for $23, shipped works perfectly also.

I'm never looking back.
