Anybody know if the front springs on my 68 Cutlass are pig tail or flat ground on the top? Before anybody gets after me "BUY A CHASSIS SERVICE MANUAL " I did, it's at home, I'm not. Thanks.... Gil

good question
I vote for pigtail, by feeble memory
but, as I may well be wrong, don't decide anything based on this

A peek at the shape of the frame where the top of the spring sits should show if it has the pigtail recess or more of a smooth seat.

That's what I also thought but the guy downtown at the spring store told me his book says flat.

They are Square on one end and tangential on the other.

as above, square (top end) and tangential (bottom, into the A arm.

So that's flat on top, pig tail on the bottom?

No! Pigtail end is reduced diameter like a pig's tail, curled around tightly. The inner pigtail hole is about 2.5" x 3". Tangential is the full diameter of the spring, 3.625" with the end coil wound a bit closer to the next coil so the end is almost touching the next coil.
