Hello 107 Gurus,
I have a gorgeous '81 380SL that has +/- 220k on the clock and has had every little thing rebuild/replaced except the rear diff. She clunks pretty bad dropping into gear.
I need some info on rear diff ratios. Were the ratios different from the 450/380/560's? If so what were they (how big a difference)? I'd like to get a nice low milage used one and it would open up my options a ton if I could get any diff from '73-89!!
Thanks!
-Matt-

buyers guide, your 380sl if us spec has a 2.47 ratio.

according to the same book, the 380se, 500se and 560 se would have the same. also presumably the sec's. as far as i know they all will bolt in. the euro model 500s have a 2.25 or so and it is posi trac., i think. but they are rare as hens teeth.
