107 Rear Diff Ratios??

[350SL4spd]

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!

They will make that clunking sound. Diffs usually howl when they are going south and they last a long time.

I have an 1986 MB 560sl with 120.000 miles. I also had a big clunk when I put in R gear and slightly lower clunk when i put in D gear. The problem was in transsmission end I dont know exatly but the mechanic changed some rubber sealing and gaskets within transsmision, also the mounting and the clunk whent away. I had many mechanics looked for this problem and each of them had different opinion saying it is differential, driveshaft mountings...The only confusing thisng is that the transsmision sends a vibration to the driveshaft and the clunk can be heard at differential witch makes conclusion something is wrong with differential....This was not the case with mine.The problem was in transmission.


I hope it this helps.
