so i let the pressure out of my front bumper shock cuz i was getting in the type two air dam, it was put on back order so i decided to get the type 3 when they release it. now i had to figure out how to put pressure back in the front bumper shocks, unlesss u can get the screw started and tighten it down in a 1/10 of a second then ur screwed.
im sure this wont be used much but for those that need to i hope it can help
(the fabrication of how to on my problem took me a bit of thinking)

so first things first, u need two pressure valve stems from diaphramed water tanks(got these at lowes)/ 1/8'' pipe tap/ type R drill (or an 11/32 will do) and a wrench or two

take the bumper off and drill your hole out with type R drill in the front of the bumper shock (dont go to deep not sure if there is a hydrolic bladder)

tap out your hole(with the 1/8 pipe tap u should make sure u dont go to deep the threads are tapered and it will self seat/seal itself)

insert air fitting and ur done/ not really

now on the bumper(pic two) drill out the center with a really big drill so the fitting will clear into the bumper

did this on my 83 280zx not sure what else this is applicable on

 

Wicked crazy (slash) genius!

 

Nice will be useful..when I get ready to mount mine here soon. Thanks man..for the pics and description.
