The car is a 1978 280se with a 6 cyl fuel injected M116 motor, I believe,
I have honestly been in thousands of benz's as I sell used parts and have
been thru bone yards coast to coast and this is the first manual 116 that I
have seen. a rare bird indeed.
I don't know the whole history of the car, but I am sure that the manual
tranny was factory.
Will the 230 bolt up to the 280 tranny?
Someone told me that the 4 cyl and 6 cyl splines are different thicknesses.
P.S. I will keep my eyes open for a manual 116 for ya, maybe they are
indigenous to Texas,lol,
