No thread is to dead to revive at least once. There has been some chatter on the forum about the need for a bolt in roll bar and specific references to the RPM roll bar. I contacted them to day to see if they are still producing bolt on 4 point roll bars for the the 370z. The person on the phone, Dave laughed and said yes we do, there is one sitting right in front of me ready to be powder coated. He was happy to here that there was discussion about there products and said if there was enough interest that he would do a group buy

.
He provide the following information: The thing that seperates us is our bar is one piece tig welded. NO slip tubes or weak points. It can be had in a 4, 5, or 6pt. ANY color powder is included in the price. Mild steel (DOM) or 4130 chromoly.
Below are some pictures that he provided me for your viewing!!!
