Be sure to run a torque strap, very crucial for a 4-speed..
Just my $0.01... 
Sorry, but what is a torque strap?

After reading all the responses, I'm thinking  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????
How about the springs???

Bent mine too - automatic car. I reengineered it with some angle iron. Also welded in a larger contact plate to my floor. No more problems after that.

 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".
Just my opinion. Good luck with whatever you decide.

I had brand new stock HD ( 3800lb ) springs in my car and still bent the pinion snubber. Obviously SS springs with their shorter front segment would help to address the wind-up issue, but I would still run a pinion snubber if I were racing the car and making 500+HP. 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.

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. 
Thanks for the info, BTW my car is very much like yours, mine is a 68 gtx and my best time so far is 11.77, hopefully these springs help and we'll be side by side

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.
The torque straps I've seen bolt to the K frame at the sway bar mount and to the block on the same tab that the motor mount bolts to. So if the tab was going to break there is actually more pressure on that one tab now instead of equal pull on all the tabs at the same time. I think I'm better off without it.

I see you're in CT... I have had SS springs de-arched before at Super Spring in Hartford. They can also add sections if needed too. In the snubber, I think it's the 1" clearance more than anything else that is allowing it to bend. I try to get mine as close as 3/8" if there's no kids/load on it, and you cna reinforce the snubber base with 1/4" plate very easilly. And the floor... prob should reinforce that too... If it's bent and stretched you are allowing too much windup anyway.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

. 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.
