jamesinc I am chasing a fuel cap for a 1977 244 DL, but oddly while one of my 1977 244 DLs uses the common screw cap for the tank, this 1977 244 DL uses the older-style cap found on 140s and I guess early 240s. It is displayed on the right in the below photo
jamesinc thepacman I did eventually find an original. There is a fancy one you can buy new: https://www.skandix.de/en/spare-parts/body/body-parts/fuel-tank-filling/cap-fuel-tank/1000928/
