No hydrawlics, on rear door. Won't stay up.
Rear access door (trunk) hydralics won't hold door open. on 1994 Chevrolet Camaro
Go to your local Napa auto parts and buy 2 new rear door hatch back lift supports http://partimages.genpt.com/largeimages/236025.jpg about $30 each, If you buy cheap supports they won't last long
