Thank You 97 320SL !
Yes it's probably like You say.
The engine has over 300000 KM with original pistons and rings!
Thank You also SPARTANV!
I thought I would only remove the motor since I didn't have an hoist but it seems there are the 2 upper bolts very difficult to remove.
Therefore I'm going to remove also the trasmission..
ps I will sent to You the bracket design in these days, even better I would share on this forum the file.
(We are talking about my bracket for Rotrex C30 94 if someone else wanted to try their hand in supercharching M104980/1.)
