had to drill the top holes out to the 12 mm subaru size, then i slid the metal sleeve from the original shock into the new shock bottom. and bling! they compress 2 inches smaller, and are 4 inches longer at full extension. i forget the travel, but its about 4-5 inches more than the stock shocks.
had to paint them to show off the chevy heritage! =]
oh ya, 15 dollar monroe gas charged, they come in white.
