Stock Shackle Length? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

GM doesn't have rear shackles any longer,not even up into the '90s...I tried...a lot. I am trying to gather whatever info on differences there may be between C/20,C/10,K/10,K/20,and C/30. They referred me to the company that supplies heavier upfit shackles for Stepvans and motorhomes "to GM".
Can some of you measure center of bolt to center of bolt and state which model you have for comparison? I always assumed they were all the same but have reason to believe that may not be true. I believe the 2wd shackles are a bit longer,making for a lower ride height. Any help is appreciated.
