Reddit reviews EMS Offroad Tire Carrier Hinge and Latch

Not sure how fancy you wanna get with it, but I'm planning on using this hinge for the carrier, and this pin to keep it open on hills. I have yet to design my rear bumper, but I did the front one and it turned out pretty good. My advice would be to look at premade ones to find stuff you like and go from there. BleepinJeep has some newer videos where one of the guys builds a bumper for his diesel jeep, and a video assembling a diy rear bumper for a Comanche.

The more related research you can do the better. The best thing you can do for your wallet is mock things up in cardboard before going to steel. It allows you to see how things will look, gives you an idea of dimensions, and is a hell of a lot cheaper if you screw up. Also be sure to account for clearances of stuff like paint/bed liner, otherwils you'll have a he'll of a time trying to get it on and off.
