K10 leaf spring bushings question
 

Howdy!

I am swapping the suspension of a '78 K10 onto my '66 frame, however there are no bushings in any of the springs. I believe the front springs are from a lift kit (has rear blocks, too) and I'm not sure on the proper bushings as Rock Auto shows that tethere are Energy poly bushings for aftermarket springs except for Superlift and Skyjacker leaf springs.

Is there an easy way to identify the springs I have? I'd like to buy the correct bushings the first time. :)

I appreciate any help!
