MDC,
This might help with your chains. Mine seemed sloppy enough I was afraid when I was haulin butt to get back to the garage, they were going to catch the fender on something else in the wheelwell.
So... I strapped two bungee cords on the outside of each wheel, just ran them through the chains pulled them tight and hooked them to the other side of the wheel.
Check the picture.
It seems to be workin fine
