First, try to find the frame specs for this car. I think someone once put them in a thread here, so perhaps you can dig them out. Failing that, I'd look for a long time in business body shop because they used to publish a book every year with line drawings and the specs for all N.American cars. I remember using them. Once you've got the specs, find a decent shop with a good pulling/measuring system, a Chart, Chief, Wedge Clamp, Blackhawk etc. Pulling your car is no different than pulling a 2012 car and perhaps a bit easier as there's no HSS, boron or foam and any bodyman worth the name should be able to clamp and pull that rt rail over and to it's proper length. The beauty of the old cars is you can use heat without screwing the steel up and with judicious pulling and heating, most of the wrinkles in the rail should come a long ways towards coming out. To make it perfect, I'd drill out the spot welds and slice the outer skin off back behind the damages, dolly them nicely, or use the straightened piece as a template to cut a new rail side out of 18ga. steel and reweld the seam and button welds. Grind, seal and paint it. I don't know your local rates, but up here they run approx. $60 per hour and I'd estimate this as an all day job, so figure $500-600 ball park if the shop's being fair with you, plus let's say $75 for shop materials. Good luck
