What's it take to do the shocks on the F&R of our MK3's? we have a 90T w/out the adjustable stuff. I bought some Monroe Sensatracs and got a $90 mail in rebate (advance auto). cost me about $20/shock!!! Do I need a spring compressor? what kind of shocks do we have? I never really looked. just trying to size up the job, never did mk3 shocks before. I did them on my mk2.... strut cartridges up front and regular old fashion shock mounting in the rear.
