i built mine in 1990 and we didnt have the resources , like the internet and forums . I rubber mounted it using the eyelets off the front shocks of trx . the frame never broke but the grab bar did 3 times before I got rid of it . Ct made the pipe and Allan said it would run the same as it did in two wheeler , that was not true by any means . My project was a total disappoint as was the people I knew that had done it before . Im glad you are happy with yours but I would still recommend not doing it .
