i got my ORD 2 1/2" flip. it suggests locating it in the stock hanger holes. my 87 3/4 ton, (don't know about the blazers) has a second set of holes farther forward as well. i was thinking of making some longer shackles like on my front end. something like 7" for the droop, not lift. couldn't i use the forward holes and long shackles?
