No, they are not. Contact ESPO Springs, they can make you a new set and they fit perfect. I ordered heavy duty springs with 1" more lift for my 64 Sport Fury. Fit great, improved the ride, and gained a little clearance for my tires. Love them!!!!!

I bought a 63 Plymouth Belvedere hardtop today and I have a new set of E body springs but I couldn't remember if they were the same length as an early B body. My wife and I visited a show in Russellville, Arkansas this weekend and there were a couple of early Mopars that attended. Nice show for a small town event. She coaxed me into going there to hear her favorite band, but I made sure we hit the car show first. Here's a few pics from the show. http://www.flickr.com/photos/12735041@N07/sets/72157619265135725/ Gary F.
