Well since I tapered the bed I don't need this anymore. It is my swing out tire carrier/ tire gate for a pickup. Don't know If it would work on a blazer or not. You have to remove the factory tailgate and drill a few holes to mount it. It is 1 3/4" .120 Dom so it's stought. The hinges and the latch pin holes are all made with the fabricators greasable bushings from DIY4x. I made a lockable plate for 8 lug wheels but it could be drilled for other patterns. Any questions just ask. It wasn't cheap because DOM is pricey so I am Asking $400 Its been tested pretty hard at Moab and held a heavy azz 37" Krawler without a problem. I think that it would handle a 42" or a 44'' without a problem.
