W123 300D auto to a manual
 

I was given a 1977 300D and love it. It was babyed since it was new and my grandparents were the orig. owners. Its a automatic and im in my teen years so im looking into converting it into a manual. I have heard stories about this automatic 617 having a different crank then the manual. I am wondering if this is true and if not what would be a good transmission that would fit this car (with a modified driveshaft of course).

a number of folks
 

have converted using 240d flywheels clutches and trannys. it may be necessary to check balance on the fw for neutral balance. i had mine checked it is neutral from factory, but factory service manual says it is balanced with the crank.

good luck

i have gotten

Thank again
 

ok i think i'll have all the parts i need but im still in a pickle because what im told is the auto 300d has a different crankshaft blot patten then the manual 240d i plan to put in it (same year). can anyone point me in the right direction so to speak. any help would be greatly appreciated.

i am pretty sure
 

that that is not correct. we are talking of the bolts on the crank right?

Yes Sir
 

i am talking about the bolts to mount the flywheel to the crankshaft.
