What's the availability for bolt-on accessories for 2006 and earlier? I was researching a Gobi-X rear bumper, and it was listed at 2007+ only. I thought it might be a one-off for that company, but I've flipped through a number of vendors of bolt on stuff as well as suspension components, which all listed compatibility as 2007+. How much is being 2006 or older going to limit tweaking my 76? Are there workarounds?
