Default Front coil springs Original?

Taking apart one of my 70 GTOs pulled this out look to be original any thoughts? Part no# looks like M&M 5386 LH and M&M 5390 RH Also the top spring is flat.

MOOG part-#´s.
5386 was 17.00" free height when new. 2043 lbs load.
5390 was 16.63" free heght when new. 1952 lbs load.
Bar dia. are the same .656" on both. Inside dia. 3.63" on both. Install height 11.00" on both

Let me guess 5389 was on drivers side?

factory front springs are easily ID'd by having one end of the spring having the coil end bent in and then milled flat so the spring can sit dead vertical.
