you may want to also consider a bolt-in bar,like Autopower.they migh not fit as tightly in a stripped car,since they're designed to work with the interior still in(although it sounds like you're keeping it anyway).they're relatively inexpensive,and you should have it in a a week.i've installed a few of them,and they always fit well
i have the street roll bar in my coupe that i got about 10 years ago,which i recently added my own diaginal bar and harness bar,then i'll be adding door bars before going back to the track this year.
if you ever want to take it out to sell the car or do interior work,you can have it out in no time.
