Roll Bar Question

I have a 79 Malibu, currently i have the entire interior out due to some rust in the floor pans i fixed and a new insulation and carpet install i plan on doing.

i figured that if i was going to put a roll bar in now would be the best time to do it.

i dont want to cut holes in my back seat. does anyone know where i can buy a 6 or 8 point roll bar that has back bars that bend and go through the speaker holes in the turtle deck?

any help would be appreciated.

If you have a local speed shop you can see if they can cut and bend some tubing, if not they can probably tell you who could near your location. The tubing needs be 1 5/8 inch .134 wall.

The follwoing assumes you would like a legal rollbar for drag racing NHRA/ IHRA:

Actually the tubing needs to be 1 3/4" (.125" thick) for a mild steel roll bar and 1 5/8" (.125" thick) for a mild steel roll cage. The tubing you get in the kits is usually .134" to gaurentee that the thickness passes the minimum sonic check thickness.

You may be able to use 1 5/8" for chrome-moly roll bars- I forget. Call a roll bar/ chassis manufacturer before ordering anything!

When you get the roll bar/ roll cage, the rear bars will be straight. You can get a kit with longer "street" rear bars that allow what you are looking to do.

When I put the rollbar in my Nova, I wanted the back bars to follow the rear "c pillar" and go through the package tray near the corners of the window. Thus it is nearly invisible from the outside and allows use of the back seat.

I bent some metal conduit in the profile of the rear bars. Took conduit and tubing to local chassis shop. They bent the tubing exactly as needed for maybe $20 for both. It was rediculously cheap!
