Dan,
When will you guys have a 1967 to 1972 B Body leaf spring out to market? Any testing going on now?
Leafs for that application have been available for a couple of years now. P/N is 24366, that includes the front Drop (raised) hanger. Rear shackle is separate, but looks really cool, P/N 17367
We are in the process of 62-65 B-Body and 63-65 A-Body stuff right now.

It's just the checks and balances in the process of releasing product. To give them credit where it's due, they won't list a make model combo until its cleared R&D twice.

So what is better to do take the extra 1/2 leaf on the right spring or buy two new left side Mopar XHD springs?
If both of your current springs are identical except for an additional half leaf on the right spring, then I'd just remove the half leaf. If they are an offset mix, like an E body Hemi pack, then it may require more mixing and matching to make them identical. It costs nothing to look at this option and if you can make two identical springs, it saves you the cost of buying two new springs. BTW, I think most retailers sell XHD springs as a pair, not seperate. So you would have to buy two sets to get two matched springs, but ask, they may be willing to mix them up.

Wow it has been too long since I put these springs on the car. I was going by the assumption that super stock type springs were only built in the A body length.
I was wrong on that one. Check out the picture here of the old springs that were on the car. Needless to say these will be up for sale, These springs have a huge arch compared to the Hemi XHD springs.
Correct Super Stock competition springs were only built with A body length front segments. It is part of the function of the antisquat that is built in to them. After 40 years and multiple users, it is really hard to know for sure what may be under a car. Are they modified OEM, are they an aftermarket SS rip off, or soemthing else? Heck, even the Chassis book tells you how to create hybrid SS springs using an original length main leaf with the balance of the pack being from an SS pack for classes where relocated hangers are not allowed. This is what your springs look like. I bet if you take them apart, you find two centering holes in all the leafs under the main leaf.
As far as the rate you want, that depends on several other factors in your combo. The factory XHD spring packs tend to be around 140#. XV has said their four post test suggests a lower rate is needed for balance and the Hotchkis units also appear to be a lower rate based on their leaf arrangement, althought I have no first hand experience with either companies products. The kit car program from way back suggested 120# leaf sets to match up with 1.1X t-bars and 1" front sway bars as part of the oval track handling program. Mopar oval track leaf springs are still offered in the same 120# rate with zero or 1" arch. However, you could get there by altering leaf counts and checking rates on your existing springs.
All depends on what you want to do, spend money or spend time. You can build effective leaf springs sets at home, but you have to have multiple sets to start with.

Our rates vary.
