I don't know about your year, I have an 89. I just put one in and like it. There's a fair amount of grinding to get the bars to "notch" together good. But I highly doubt any cage/bar will go together with very little work. You'll need to cut your door bars to whatever length you need them depending on the angle you install them at, how far forward you want them to go, etc. They just pass through your shoulder to elbow on your upper arm though. The biggest pain is getting the angle cut where it meets the floor up by your feet.
I'm sure some other brands may go together easier, but my S&W is pretty good. They may still be on sale too. I paid $109 plus $65 shipping. Very reasonable for what you get.
If you can weld good go for it, because $1700,,,,,,,,,,,,,yeoooooooooouch!!!!!!!!!!!
Crap I'll drive to your house and do it for half that plus some Taco Bell.
I painted mine with Semi Gloss black Rustoleum. 2 coats and it looks sweet. You could use that POR-15 paint for a more durable finish. I've heard some good things about that stuff.
Just be prepared to do a lot of welding in tight areas and on the thin floorboards. I'm fairly new to welding and didn't have any problems so it's not as hard as some people say. Watch for fuel lines, undercoating, carpet, etc, and have a fire extinguisher ready. I used compressed air to blow out any small flame-ups and to help cool areas down fast.
Here's the link:
http://www.swracecars.com/ looks like they're still on sale.
If you get one prepare to spend at least a half hour removing the thin sticky tape they wrap it with and cleaning the tubes.
My experience is they're a great company.
