G-boz has some bars for sale. They are referred to as Monte Carlo bars also. His for sale thread is in the for sale section on the 2nd page. If you don't have a jeep steering shaft and you are able to buy one, its a great upgrade from the rag joint. Good luck.
I got my bars from an 84 Bonneville believe it or not. If you can find them in the junk yard they also have the jounce bars on most of them. What year Jeeps are you guys getting the steering shafts out of? I am headed to a Pull N Save next weekend that is about a two hour drive so I want to remember to look for one.
