    I'm in escrow on a beach home that I own/will have owned in San Clemente CA, and going through things which I have stored there I discovered that I have a 3.07 LSD and a 3.64 open differential. The 3.07 is casting marked E24 and the 3.64 came out of my '71 Dietel Alpina Bavaria. Both will fit right into an E3 or an E9. I need to move them this weekend to my home in Pasadena CA, and am curious about the value of the LSD if I decide to let it go. I have not opened it up, so don't know the condition of the innards, but I do know that it sat on that darned bench since 1998!

    As a core- no idea of condition- 600.00
    rebuilt - 2500
    clutches, bearing and seals with a good gear shop is 900.00

    Keep in mind that the LSD unit is NOT interchangeable with an early side loader.

    Wait
    If it’s $2500 rebuilt and $900 to rebuild, the. Isn’t the core worth $1600?

    No it’s not.
    Unless your time is worth nothing.
    And you get free gas.
    And a free truck.
    And free insurance
    And it’s Re-buildable and not just an 80# lump of junk.
    And you don’t pay for rent on a shop.
    And you don’t pay for insurance.
    And electricity.
    And gas.
    And it’s a perfect world where nothing gets damaged in transit.
    And you never get sick or hurt (maybe loading that diff into a truck)
    And you don’t need to send your daughter to college.
    And it sits in your shop for 3 years without selling....
    And you don’t care about your reputation so when it shows up broken you tell the buyer “Too Bad”

    @sfdon - so the 3.64 that windnsea has will NOT bolt directly into my 73' Bav? I thought they did, especially since it was in a 71' previously. Thanks and sorry if I am not understanding properly because mine is a side loader, standard Bavaria diff. -best of my knowledge. Not interested in the 3.07. I am right next door and could pic it up, if it bolts in not knowing condition just taking a chance it's still good since they were pretty bullet proof right? What would you say is a fair price?

    The issue with early vs late side loaders... they both bolt right into a coupe with no problems except the hardware to the flanges is different. Not a big deal.
    The problem is with what’s INSIDE.
    You cannot install a late LSD unit into a early gear set.
    Not compatible.
    A good 3.64 core is worth 200 bucks

    Don - so the 3.64 is considered early correct? And it should bolt in to a 73' Bavaria? Or do I still have that wrong? Wait nevermind, I was thinking the 3.64 was a LSD too. May bad. I just read it wrong.

    Don can chime in if (when) I am wrong. It is my understanding that there are three different sideloader cases. The cases all fit in e3's, e9's, e12's, and e12 based e24's. The internals aren't interchangeable though. A 3.64 likely spans at least 2 of the 3 generations if not all three. The 3.07 came with the dogleg, which has behind a 220hp motor with a 1:1 final drive. So it is very tall. Since it came late, you can't swap the LSD onto an early R&P and turn a 3.07 LSD into a 3.64 or 3.45. Now if you found a late model R&P from say a 528,628, 530,630, or a 533,633 then you could swap the internals.

    Without getting the specifics right, I believe there is an 8 bolt case, one with nuts and bolts, an 8 bolt case with no nuts (threaded housing) and a 10 bolt case with a threaded housing. Correct @sfdon or no?

    I think that "back when' I got ahold of the 3.07 it was going to be a back up to the 3.45 which is in the car. The trans is a Getrag 265/5. However, this 'forever a project' will be on the road and should be quite capable with the larger engine. Can't wait to start draining that 'North of $4.00/gallon gasoline' out of the tank - er - my wallet.

    I call it (dumb as it gets) -early early, early and late.
    First 2 are fine to commingle. But only the case is the same on the late version.
    There are 3 different flanges.
    And the flanges can bolt on or they can snap in.

    So...

    If you have a dogleg....the 3.07LSD will bolt right in correct?

    Curious..... ;)

    Different in/output splines (flanges/pinion) early to late, so they need to 'match' the diff unit itself - especially re SFDon's note on bolt vs snap. Early also has additional bearing on output flanges; easy 'upgrade' for later. Crown wheels have different bolt configurations, 8 hole vs 10 hole, m10 vs m12. I had 8-hole crown wheels at m10 and m12! I've bought maybe 10-11 LSD S/L's, 4-5 open plus quite a few CW&P's only over the years to compile all my needs for 2 race cars. Differences in the case also, as i recall, 3 types.

    Not come across CW/case with nuts. Complete internals are interchangeable within cases but need to take heed of SFDon. I've done much of this. The later/common 3.07 LSD units are difficult to find CW&P's for with them being 10 hole. Nevertheless i have found 3.45, 3.64, 3.91 to fit them. The most adaptable LSD unit has been the earlier (40%) with 8 holes, i found a few 8-hole CW&P at various ratios, had them drilled out to m12.

    Don't forget the Klingenburg vs Gleeson also :rolleyes:

    There is also

    3,91
    4,25?
    4,44
