Sometimes you can shop around and get a cage installed for a very reasonable amount. I realize that this may not be possible in Wyoming without driving a considerable distance. In my case I had a 8.5 cert chrome moly cage done for $1,500 parts and labor. That included two swing-outs. Other places wanted $3-4K for the same work. I did have to tow the car 200 miles to get to that shop, but it was well worth it.
