I wrecked my newly acquired J10 and then recently while putting it back together, it was discovered the top leaf of the passenger side front spring is broke.
I sorta started asking about this in another post.
provided some good comments (Thank You!)

I think you could use the main leaf out of a waggie pack and not know the difference when you are done and not have to do anything regarding lifts and the such.

Yes, they all have 4 leafs, but have been told some springs are rated different than others.
Like a SWB, I6 powered J10 will have lighter springs rates than a LWB, V8 powered J10.
Looking at the GVWR for J10s and Wagoneers in our Tech Library, the ratings are very close.
I know my #7600 rated J20 rear springs do not hardly ever flex...and I've towed some monster loads.
I would hate to think about the #8400 springs!
But, are the front J20 springs different than J10/Wagoneer? I dunno.
I recently purchased from a fellow member a set of front springs from a J10 that was a long wheel base and powered by an I6.
This donor is a late 70s J10, while my J10 is an '82 model.
I've been talking to several folks...all of whom give me a different answer.
My basic questions still remain to be answered or confirmed.
1. While the GVWR of J10 models vary, are all the front springs the same spring rate?
2. Is the difference in GVWR is made up with rear springs of different rates?
3. Is there any difference in Wagoneer front springs rates and J10?
Long term, I am thinking of maybe dropping my 6.2L Diesel into my J10, making it a semi Daily Driver.
I am wanting to not have any issues with a 6.2L overworking light duty J10 front springs.
Also, I may want to do some towing, especially if a drop in a Diesel, and do not want light duty front suspension bobbing up and down under the stress of a heavy trailer.
Thank you for your patience while I wrap my weak mind about these concepts.
