1979 Toyota shocks

Alrighty Toyota guys... What shocks are you running for your older trucks?
 
Mine is a "79" model pick-up and I am having a hard time finding shocks for it. I can find factor shocks, but I want some lowering shocks.
 
Any help would be great!  Thanks!

No old school Toyota guys???     I know there are a few of you out there...

Measure you extended/collapse length and subtract your drop and look in Napa Shock Catalog. Thats what I usually do. -ryan
