I replaced the front coil springs on my 1947 Plymouth Club Coupe. After installing a Mopar 318 V8 engine the extra weight on the 65 year old stock coils pushed the car down near the bottom control arm bumpers. The car would bottom out alarmingly on moderate road undulations and potholes. An friend of a friend gave me some mystery coils he was never going to use. I have no idea what car they were used in but they were NOS, in the box, and the numbers on the Mopar labels were 71765 and 52039056. The price was right so I tried them out. To my surprise they were the same diameter and height as the stock ones, but seemed stiffer that the old ones. After installing the new springs the car sits at least two inches higher and the ride is much improved. I lost the low stance that I liked. I may go do some follow up work and cut a coil off both springs to get a little lower. I think the stiffness of the springs will prevent bottoming out even if I lower it a bit. I'll try posting photos.
