In my quest to upgrade the SIAM with a newer gearbox, the Sprite Ribcage Transmission, I came across this article in the “Tin Block Times”. Tim Foster gave permission to post this article for others that maybe interested in doing this for Crosley or Crosley powered H-Mod.

Originally published in the “Tin Block Times ” Volume 1, No. 1 Winter of 1986 author Dr. Bob Graham and additional info added by Glen Brynsvold after he completed his upgrade to the Crosley-Scorpion
