I have wanted to manual swap my 560SEL since I first got it.
There is a M117 manual bell housing for sale with the P/N 1172512601. What car is this bell housing from?
What else do I need? I know I need the pedals, clutch, transmission, modify driveshaft, and modify transmission mount.
The pedals are only available from a W126 280SE, but for the rest could I just buy a manual 190E parts car and swap everything over, then modify the driveshaft and be done with it?
Here are pictures from the bell housing:

I don't believe that bell housing is for a manual transmission. To my knowledge no M117 engine left the factory with a manual transmission.

The only Mercedes V8 available with a factory manual transmission that I'm aware of was the W111 with the 3.5L M116 engine.

I'm not a Mercedes guru so I'd be happy to be wrong about this.

AMG made their own bell housing for their manual 5-speed conversions for the W126 and W107.

The guy I bought it from states that it came from an r107 V8 manual. These did come equipped with a manual transmissions.

No V8 w126 was EVER offered from the factory with a manual transmission. Lucky for us, MB did have the manual option for the straight 6 models. That means the pedal assembly is available for the W and C126s as a direct bolt in. You will NOT find a direct bolt on transmission for the M117. AMG made their proprietary bellhousing casting that was to be mated to the Getrag 265 transmission. That was commonly used in period BMWs.
On the AMG Classic site I’ve posted all that’s needed for the conversion.
Good luck!

Member Fonzi would know if any R107’s with V8 came with a manual transmission.

It looks like a few W107 V8 (the 350/450) cars came with a 4-speed manual transmission and only the 6-cylinder ones came with 5-speed manuals.

Never a five speed. Only four speed was available from MB for the V8. Period. The flywheel from those V8s is used in the period correct swaps like the one pictured above. But that too needs machined as it’s larger, and needs cut down to fit the M117. I’m in process of doing an M120 swap into my SEC with a manual 6speed. I may end up selling the kit and it’ll be posted here

So far I have been worried that the bell housing won't fit my aluminum M117, but while searching for matching transmissions all other bell housing had P/N 1172512501, while the bell housing I have coming is 1172512601 and the seller stated multiple times it will fit the aluminum engine.

A manual transmission that has the bell housing and transmission separate is needed. I am leaning towards the original 4 speed V8 transmission, anyone has any experience on how it feels? I found a dirt-cheap /8 4 speed that would fit, but can it handle the power? I have also found an upgraded 5 speed which would fit, but don't have the money for it right now. I am probably just going to get the correct V8 transmission.

Can someone steer me into the correct direction regarding the flywheel?
Anyone selling W126 Clutch Pedal Assembly?

Ebay Germany, or Roland (longtime member here) is your best source for the pedal assy.

Sorry guys but Mercedes made a bellhousing part number 1172512501 for a V 8 engine the M 116 model for a 4 speed also for a 5 speed.
There where some transmissions available in Hungary on E-bay several years ago.

Pre Mercedes merger AMG had custom ordered from ZF limited numbers of transmissions and installed in W108/9 + later W116 6.9 for 24 hour endurance racing.
They were dog leg shift pattern.and not sold to customers. A family friend whose hobby were horses (had several hundred) was close to Hans Werner Aufrecht through shared equestrian interests, and had one of those manual 5 speed in his 6.9.

I used to be the designated driver.
