I took these out of my 71 GS.I wire wheeled and painted them.They where a little to high for my liking.I don't know what kind they are,but they are about 2" higher than stock.You can see the extra ring in the spring.The car sat 27" from the ground to the bottom of the wheel well moulding with 255/60/15 tires. $40. plus shipping. A before shot with these springs in the car. [ An after shot,difference is minor,but new spring are not broken in yet.You can see the top of the tire in the before pic with the springs for sale.They're good for bigger tire clearence.
I'm not sure.You may need to ask somebody on here that question.I know if you look up rear coil springs,autozone gives 2 different #'s on 69 and 71 gs cars.Please let me know soon,your up but have two waiting.Thanks,Tom.
