Im not up to speed on springs! .Springs for Dummies. ha. This is what Ive gathered..

So 67-72 tapered springs are no longer available nor made..that is tapered 3" at eye to 2 1/2 at axle pad. Most 73+ are 2 1/2 wide..factory was 2. 3/4.
Tapered can mean both width of spring as well as thickness. Duh(needed to look at a bunch) Tapered thickness is a higher quality spring/pack. Makes engineering sense anyway. The Dormans are non tapered from pics..affordable. Springs seem to taper (width)towards the eye...This seems to affect size bushing needed..at least the shoulder. Be nice to have 3" at the eye with ¼" of bushing on each side to fill the 3 1/2" space. Or use fat washers. I'm preplanning..want to use stock as I want mostly no lift running 32" tires. Springs have 2 different style clips/retainers. Bolt style may not allow movement. Arguments against other style. Other springs have riveted on teflon liners on the leafs..I think on tapered thickness springs only..hmm interesting idea.
So there is a lot to say..
Need a podcaster to do an expensive..buy all the different types and do some kind of analysis. Many of you have said alot about your experiences..thank you. It's useful. If I wanted a 2 1/2" lift I'd buy the skyjackers...seemingly best reviews. Toughcountry in there somewhat.

For now since I can't find a used pair. I plan to buy the Dormans for temporary fitment. Go from there. Next option down the road would be custom springs as it seems there is little choice for stock springs.
Info is power..my engineer brother says!
Stock leaf's and replacements all pretty much act the same. Even the ones labeled "soft ride" IME. I personally have seen at least two sources for stock type replacement springs on the web not including Dorman. Which probably gets springs from someone else.

The catalog Deaver's I used for mock up and my custom made Deaver's have sliders at the ends of every leaf held in place by a button on slider and hole in leaf, no rivets. The four spring clamps are fastened to a lower leaf and a bolt goes through the top of clamp.

If your main objective is low cost just pick a set you are comfortable with and use it. There will be little to no difference in where you get them from. I have been there in my younger years and I was content with my decision at time.
