I'm looking to pick some of these up today. Has anybody ever had experience with the autozone brand springs like these?

They have them in stock here in town.

I can get these:

But they have to be special ordered.

They appear to be pretty much the same........can anyone offer words of experience here?

i had the progressive rate ones (for sale now). they made a big difference in the way the car rode over the cargo springs.
not sure if they were still the cause of my wheel hop. but i since swapped to some 5x11 circle track springs.

I suppose any springs that are new will be better than the worn out old springs that they had used the coil spring boosters on :)

Your car ride height will change with new springs so be prepared, my 72 went up 3 inches.
