I bought a 2002 manual chevy cavalier w/ shaved doors and poppers and now the poppers dont work so i was thinking bout buying new ones and i was wondering for sumone who has got them installed.....I no it depends on the company that puts them in but i was just wondering around how much does it cost????

the popper itself? you can find them pretty cheap on ebay.

Some people swear by Autoloc, some swear by SPAL, some swear by AVS........all a matter of preference I guess......................I personally have Autoloc poppers.....and they are easy as f*ck to replace.....just 2 screws..........
unless you mean solenoids/actuators...........which are still easy to replace/install.....and I personally have 100lb (only really need 35 lb) Autoloc solenoids. You can get them from www.suicidedoors.com and other places including www.gaugemagazine.com and places along that line...................

Old hot rodders use SBC valve springs for poppers. Build a pocket, add a striker and there ya go.
