C3 Spring Tag

[Gerard Q.]

The JG lists two green paper tags for the front springs (HS or HT) for 70-72 350. I have a 71 s/b auto vert w/air....which tag would be correct for my car.
Thanks in advance.

Re: C3 Spring Tag

The same! GM added up the spring weight of options looked at a chart and selected a spring to match the combined spring weight...in 70-72 HS was the light duty at 250 lb/inch while the HT was slightly heavier duty at 264 lb/inch probably indicating more options like A/C.
