That rack fits just fine, installed mine on Sunday. It comes with a couple of big rubber spacers that are to go between the inner and outer lid surfaces, the GL 1800 you can seperate the two parts. Don't know how you would get those in on our lids.
I talked to the guy I know here with that rack, he says that he had a dealer install it, and they put in the spacers I referred to. I don't know which dealer or how they did it, but I intend to find out.
He also says that he has used it on a couple of long trips to Sturgis, and to Laughlin. Says he is sure that he overloaded it, but now problems, no cracks, or damage of any kind.
I think that the best place to buy it is probably from Hal at directline; that is where I got mine.
