My advice would be to call Wild Rides and find out if they supply instructions. I bet that if you showed an interest in their product, they would be more than willing to talk to you about self-installation. I can also tell you that I saw an installation article some time back in either MM&FF or 5.0 Mustang mag. but I can't remember which one or what issue.
My advice on a 6- 8-point roll BAR: Don't buy a cheap one! Seriously, if you plan to do this one yourself, your best bet is to look at something like an S&W piece. If I remember correctly, I have heard positive things from other people about the S&W piece. Check out

I hope this post will give you a little jump start. You are going to have to do your homework and a little bit of research on this one, though, if you want specific answers to your questions.
Best of Luck!
