spring hanger from 2wd for shakle flip?
 

can get complete springs and hangers off a chevy 2wd, ive heard the front spring mount will work for rear shakle flip, need to know more on this.

Also have been toldd if adding the spring pack from one of these 2wd's to the front main leaf will add 4", need to know a bit more before i buy these/waste money?

ill also get some pics of my new 36's and rims with stock ride height, they fit but rub if i turn in the front

You mean the front spring mount of the rear springs right??
and it depends on the year also

Here are a couple of threads that have talked about this recently.

One of them has a link to my '86 blazer with the shackles.
