I've used all of the above and they are ok, but the best kit I've found is the clevis type offered by Applied Racing Technology in Fla. ......Much stronger than anything I've used before............check it out

I have a swing out bar in my car with the Applied Technology's clevis ends. It works great, the only thing is that you have to install a stop for the bar when it's closing, also drill some hole in the roll bars so that you can roset weld them. I can also take my whole bar out if I need to with in seconds with the use of push pull pins on both ends.
