I considered my fathers 1961 Oldsmobile to be a "modern pro street". It started as a prostreet car but luckily we got through to him. He got hooked up with colorado customs and installed a set of 18x8s on the front and 20x12's on the rear. I would have to scan the image out of a magazine to show the lips but damn they were huge. I sure do miss this car.... Rumor has it the new owner converted it back to pro street, such a shame as far as I am concerned.
