I have a T-Top 98 Trans Am
Any suggestions on a manufacturer?
This is something I will install and weld myself.
I would like to get a ChroMoly set-up.
thanks

You only need a 5-point bar from 11.99 to 10.00 in a non-convertible (the passenger side bar is optional, and either door bar can be a swing-out). This is of course provided you have no floor, frame or firewall mods to your car (wheel tubs or mini-tubbing is allowed). I choose to leave the passenger bar out of my car b/c it allows for easier access to under dash on that side with no bar in the way, and even if you get a swing-out and unbolt it, it's still a PITA compared to no bar. Most guys get them for chassis stiffness, but I'm running subframe connectors already. This is another point of why to weld instead of bolting: for chassis tie and stiffness.
However, you are allowed to bolt-in a rollbar.
The 2004 NHRA rulebook quotes: Unibody cars with stock frame and firewall may attach rollbar with 6-inch x 6-inch x .125-inch plates on top and bottom of floor bolted together with at least four 3/8 bolts, or weld main hoop to rocker sill area with .125 reinforcement plates, with plates welded completely.
As mentioned these are NHRA rules, I believe IHRA requires a 5-point bar at 11.50 to 9.50 with the same requirements on frame, floor and firewall restrictions.
