I recently replaced the rear springs and all the shocks on my 91 G-20. Had to let them soak with Areo Kroil for few days (sprayed them twice a day for a week) but was able to get all the bolts loose (in a couple of them used a piece of metal pipe on a 1/2 inch breaker bar for more leverage) but was able to loosen them all up, at that point more shots of the Areo Kroil to let it soak in as I turned the bolts…..seemed to work very well…


Recently purchased (10-2021) a 1991 Chevy G-20 “Shorty”. Past vans are a 1976 Chevy G-10 (purchased new in 1976 & sold in 1995). A 1978 Chevy G-20 Shorty purchased in 2010 and sold in 2015.
