Sloper pushrod tube springs

[Phil Hartshorn]

Hello All.
I am restoring a 1930 500 Sloper, and have found that I have none of the 2 pairs of springs that fit inside the pushrod tubes.
I have got to get some other springs made, so could someone let me have the following info? Overall length, outside diameter, wire diameter, and number of active coils. Or any spare ones for sale.
Regards Phil
