Overriders for my 65

I got the original aluminium overriders for my 65 back from the chromers and have refitted them for the first time in over 25 years and they look great. At the same time I removed the tow bar and was amazed at heavy it was and also how heavy the later metal overriders are compared to the earlier aluminium ones. I might save a mile per couple of gallons and be able to save for a holiday on the fuel saved!
