That looks stronger. I need one for a Dana60, Where can I get one?

that I should change my 42yr old springs. My car is a 68GTX so the springs on there now are what was HD then and the pass side has one more leaf than the driver side. What should I buy, Super Stock Springs or the Extra Heavy Duty Leaf springs or something else????? Where should I buy them????

Be sure to run a torque strap, very crucial for a 4-speed..

How about the springs???
I don't know what kind of car we are dealing with, so I'll make this comment be a "general" response. If you drive your car mostly on the street with an occassional trip to the track, then HD springs will do just fine. With a "B" body, be careful with the weight rateing. You want the heavier rated spring to keep the car "level" or a little "up" (raked), in the rear. If you decide to go with SS springs and have a "B" body, I use the 002/003 springs, "for a stick car". You will have to relocate the shackles foreward for proper geometry. Snubber will not be required with either choice. With MOPARS, the front spring segment acts like a traction bar because it is shorter than the rear spring segment, and WILL NOT "wrap up". The pinion snubber was installed by MA MOPAR to compensate for too much weight in the car, thus keeping the rear from "bottoming out". 
Quote:You are also correct. I forgot to mention that, thinking that this was a"given" and everyone knew this. My bad! And not ALL SS springs need the rear shackles relocated, JUST the 002/003 going on a "B" body car. This is because the 002/003 springs are "A" body springs, but work really good with a stick car.
BTW, it's not the shackles you have to relocate with SS springs, but the front spring eye mounts. They have to be longer (towards the rear of the car) to make up for the shorter front spring segment.
. I ordered the 454/455 because they were for B body and I don't want to relocate my rear shackles. Why whould the A body springs(002/003) work better??? Oh, Summit is on to us with the 10% code, It didn't work on line so I called them to place my order and they told me that "their codes leaked out onto the internet so they canceled their codes" (that's funny, how could that happen)but I told them I got it out of the NY Hunting Guide and still got the 10% off.

The 002/003 "A" body SS springs were what was used on the old school "A" and "B" body stick car Super Stockers. Because they are an "A" body spring, they require the smaller shackle. Also, because they are an "A" body spring, the rear spring segment is shorter and this is why the shackle needs to be relocated. These springs are rated at 3000#, but lifted my car up over 2". I use solid lowering blocks to get the ride height that I want.

A strap is not a bad-idea even with solid MM's.
I have seen and heard of people breaking the tabs on the block with a hard-launching heavy stick-car.
