i may be getting a roll cage for the Z, and was wondering how much it would run to have the welding done? i figure i'll be doing all the removal of the interior as well as the cutting of the interior to put it back in.
i just need the welding done.

also what has to be removed for the rear bars to mount in the trunk area? most pics i see of the bars installed show the driver bar in the rear going into or very near the speaker? does it require removal of the speaker or will it fit with it in place (i understand this depends on the bar...but in general)

 

Here are some pics of mine.

Wolfe Roll Bar Install

Cost wise for me $Free.

I would expect for a Wolfe roll bar setup that's already jig notched where mainly they just have to place it in and weld it should not cost more than $300 bucks. That's assuming that you take out the interior and get it prepped for them.
