Never did one, but got very close. We almost prostreeted my Son's Capri, and did some research on it. We thought the best way to go was to buy one of the mandrel bent frame kits, and simply cut off the existing frame in front of the axle and start anew. Then we were going to use one of the 4 bar setups available, in conjunction with a narrowed 9 inch rear.

What stopped us was the cost. By the time you buy those components, plus some narrowed axles, a good 9 inch center section, and some big mickeys and wheels, you are in for about $ 5-6,000.00. We just couldn't justify that kind of money in this particular car. Maybe some can get it done cheaper, but that is what we came up with.

However, I still like the looks of a tubbed out prostreeter. Hope someone on here can give you some better info.
