I understand what you are saying but I will take a chance and see how it works with just a spacer on the hub first. Here are some of the photos I took today. The first one is just a plate bolted up.

This one shows how much inward the flywheel sits on the 560. You can compare it to the photo I posted earlier showing how it sits on the 450.

This one shows flywheel as it sits on the 450 hub, sticking 2mm out.

And now how it sits on the 560.

I cant remember right now but I think the pivot ball just screws in with a lock nut. The rod is easy enough to make a new one. If you don't adjust them you run the risk of spitting the seal out of the slave. Plus it will be pushing on one side of the throwout bearing instead of the middle which will accelerate wear on it and the bearing retainer snout.

Here it is. I think I can probably put a washer or two as a spacer to compensate for the difference. There seems to be enough meat on the thread to secure it sufficiently. As far as the slave is concerned I will take that chance. When I originally put this transmission in the 450 I installed it with the wrong slave, the short one. It still managed to partially engage the clutch. I just measured it and the difference between the two is 20mm. That is why I am hoping it won't be a problem.

The other concern that l have has to do with the throw out bearing. The one which came with the engine was still good but I decided to install a new one. I kept the original just in case. I compare them today and noticed that the newer one, after only 5K miles looks very polished/glazed. It spins smoothly but I am wondering if this wear is unusual, especially compared to the original one. On the photo the newer one is on the top.

You've gotta make sure you have it resting off the fingers fully. There's a return spring in there on the fork I believe right? You don't want it touching the clutch at all when the pedal is released.

I could be wrong, but there should be something pushing the fork back to disengage the bearing from the fingers. I honestly can't remember on the v8 car. It's been 2 years since I had it apart. There is an external slave and spring in the fintails I've been working on. I'll see if I can find any documentation on when I did my clutch stuff on my drift car.

I don't see a return spring. Can you elaborate? Maybe a photo?
@IvanGrozny

Today is a good day to get information from both Jason and me. Yesterday we wasted 8 hours together working on my 350slc with a stuck clutch and comparing slave cylinders from my 350slc and the one I purchased for a 1974 240d. The plunger depth is different, and I devised a set of ratchet extensions that I am able to use as a manual pushrod to see the resting and full depth of a clutch/pressure plate (that is stuck). We did a lot of measuring.

I wonder if now would be a good time to tear apart the seizes motor 350sl 4-speed we’ve got too. I may be burnt out after yesterday, but my mind is still spinning. Lots of fresh info on the brain. PM me if you want my phone number to call.

As I am getting closer to installing the 560 engine into my 450sl I am going over the list of parts that I still haven't obtained to enable the engine to run. One of these is a 560sl radiator as my original radiator has the upper hose connection on the opposite side and will not fit. I need a complete radiator, in good condition, including all mounting hardware, clips, buffers and mounts. It would need to be shipped to 30809. Let me know if you have one and what you are looking to get for it.

Engine in and running on djet but poorly. I think I have air leak around injectors. I have to find/ fix that and at the same time also adjust timing, idle and idle mixture. At least it started.

Nice work!

What’s in the background? I only see one 107 in your profile.
