@ Jo...Yeah i usually work with 7-10 # yellow foam for quick mockups here at work.
@ everyone else...the rear plate mold was dropped off this morning at the local vacuum formers. He's going to pull both the hitched and non-hitched versions. When i receive the parts, I'll clean them up and test fit the non-hitched version on my vx (since I have a standard hitch installed). But, will need someone (local preferred, but not necessary) who has a Tone Monday hitch to test fit the other. If all things go well, I'll offer these first two at a discount.
