I didn't take pictures when doing my L4240 and that has the adjustable wheels. I would have to write that out and it would be quick long with just a very few pictures. Now I would do it but lets see what wheels you have and well take me a few days.
No need to go out of your way, was just wondering how you went about it. I have adjustable wheels, with 4.5" spacers added between the centers and rims. Somewhat visible in this picture.
Like you, I want access to lug nuts without removing the weight, as well as my spacer bolts, in case they need tightened. I want the weight to fit snug, but easily removed.
I'll take a couple pictures tomorrow and if you would send me your phone # and good time to call, I can tell you alot better then I can write it. With the pictures I get tomorrow and us talking you might want to give it a shot.
