I just spent an hour installing my new Satin Silver Premium Export Brace from West Coast Classic Cougar. I picked it while at the 2018 WCCC Open House. I watch a couple of videos and was worried that the bolts might not line up and that I would have to rent a hydraulic portable ram to spread the shock towers apart. Luckily, I was only off by about ½ inch and was able to stick a metal rod in one of the holes at the top of the brace and adjust the export brace just enough to pop it down onto the bolts on the remaining side. Only had to use a socket wrench with three different sizes of sockets and a wrench for the brass nuts under the engine compartment lip. I didn't even have to take the hood off, although it would have made the process easier. I'm very happy with the results.
This part is built to Ford specs, which means it would have dropped down onto the bolts easily if you car was brand new. But with a 50 year old car, things have moved around. You may need to use a hydrolic portable ram to spread the engine compartment enought to get the brace to fall onto the bolts.
Overall, I am very happy with the new export brace and the car drives quite nicely. It isn't quite so loosy goosy on the cornering anymore. I like it a lot.
