will fit in passneger foot well when not in use and fill it lol
My 1970 van and Disklok have now been introduced to each other and I find that the Medium Disklok does actually fit. Snugly, but it does still slip around the wheel if turned, as it is meant to do. I will be careful putting it on and removing it to preserve the finish on my steering wheel.
Another gem I have learned re Diskloks (I do hope it's true!) is that the Large and Medium are in fact the same size. They certainly weigh the same. The internal measurements between them is amended by using packing pieces.
Hope this helps!
