modest lowering of 71 c20 rear end

[SFColbert]

From a newbie,
I've Googled and reviewed catalogues and found nothing, so thought I'd ask here. Are rear leaf spring lowering shackles available for a 1971 C20? Looking to get only a level ride with the front end so perhaps 2" would do it. I've already removed 2 leaf springs. Makes the ride a bit nicer but did nothing for the height.
Thanks in advance,
Stephen
