PN 91142. The pair retails for about 85$. intended for dodge use, but will fit chevys. Will provide 3/4-1" true lift (not like 2" drop shackles that only drop an inch). 60$ for the pair shipped, or 35$ each if 2 people each want one to help with the lean. Price not set in stone.
thats what they look like currently. id be more than happy to press the bushings in.
