Has anyone ever purchased leaf springs from springs and things.

Yes, several times. Good people who know their springs. BTW - unless you're running super stock springs, the spring pack should be straight and level with the car sitting on them. That's the way Mopar designed them and the way leaf springs work best.

I purchased a set with 2 inches more lift way back around 1999.
One of main leafs had a twist in it so bad that I didn't even try to install it. They paid for return shipping of both leaf springs and built me a complete new set at no charge. I was amazing by that, and they raised my car 2 inches perfectly. I assume the same people own the company, so buy with confidence!

Bought a set for my '57 Plymouth a few years ago, and I am satisfied with them.

I have purchased springs and other suspension parts from Springs and Things for at least 15-to 20 years. No problems , I would highly recommend them.

I just purchased my 5th set from them. I try and replace springs whenever I pick up another old car... As always, good service, good products and quick shipping....

I have always ordered the one inch over stock as already suggested. I also now purchase new hardware.

Thanks for the info i will be ordering a set this week.

Why is 1 inch over stock suggested, is it to allow for sag or just an appearance preference?

I would (surely) think it is for the sag. almost everything takes a set/ages. You can work with the front/rear shackles to adj height slightly as needed
