Hi All!...have a question for those of you who have gone thru the project of replacing/exchanging the rear leaf springs on your Imperial. I have a '66 Conv. that has neded new rear springs for some time. I am finally going to get around to taking the ones from my old daily driver 4-dr imperial (parts Car) which had the springs re-arch'd years ago, and putting them on the '66 conv. I am assuming the leaf springs are the same for the 4-dr and convertible (?) and was wondering of I needed any special tools like a acet. torch to remove the old spring shackles or just a VERY BIG breaker bar and strong socket!??? Also, I would assume (maybe a mistake in doing so) that it is better to use NEW replacement shackled, if that is an option, and wondered where any of you may have gotten them from? is this a NAPA store item or someplace special like "Spring and Things"? Any info would be greatly appreciated before I start brusing the knuckles and using colorful language. Thanks, in advance, to all for your time and patience. Dan Melnik
