SS spring identification

[bballfan1]

I have a set of SS springs with a part # of 2403853 on the left. Can someone tell me exact application? Also have the matching right but part number not visible?

 

[1968rt]

That number doesnt look like a SS number. Here is a list.

Measure from center of front eye to spring pin should be 20". If not probably a regular spring.

20" these were in a race car for 45 years that was never raced.

Probably before S/S springswere given P before part number. A p/n that starts 24xxxxx is around 1964.
