If you want to retain the full interior AND have a legal bar or cage that you can live with in a driver, have someone who knows what they are doing bend it up and install it. IF the car will not run quicker than 11.50, you may get away with a less than legal bar which will provide some degree of safety beyond having having nothing. Any kit you buy will be a basic deal made to pass tech, be cheap, be easy to install and nothing more. Yes, it will cost a little more than having someone slap a kit together. Don't forget the frame ties.
That's what I'm doing with my street car, I'm having Chassisfab Performance in Tallmadge Ohio do a custom 6-point bar for me, the door bars will be bent like a pro-touring car to conform to the seat and still be able to keep the arm rest. I'm only planning on running 10.90's at best and will only race a couple times a year. And I know the door bars will have to start up high between me shoulder and elbow.
I really like that door bar 69lawndart posted, with the added gusset type bar in his photo.
