I have for you a wonderful opportunity!! I have a chance to offer you a nice 4 speed manual transmission for a 1981 240D. Will fit 1977 to 1983 240's. But also now is the chance to replace the transmission in your 300D to a 4 speed manual. I have all of the necessary parts to convert an automatic to a standard. 186,000 miles on it, shifts great.
$300 for the transmission only.
$50 Additional for the clutch components, (Shifter assembly, clutch slave and complete flywheel with clutch plate)
Shipping is not included, I would need your zip code to tell you exactly.
Please don't hesitate to ask any questions!
