I am trying to find what leaf spring I have for my truck. I found a paint stencil number on the top of the front driver side spring. It is TCI-T3LM. I have tried searching but can't find this part number off the web anywhere. My springs have 3 leafs. I don't want to pull the springs out and measure and then have to repeat once the new springs come in. Thanks for the help.
P.S. Feel free to post any suggestions or opinions on what spring you think I need.

 

I think TCI is tough country.
