Aftermarket Gauges Needles question

[squeals99]

alright well i got my new gauges installed and had to pull the needles off to get them on... drew a picture of where everything was, and also took pictures with my cell phone to see where everything was... so after putting the needles back in their places, now the needles arent accurate.... so is there any way to tell where the needles need to be placed? like anywhere to look for inside the little hole or anything like that? i have pics of where everything sits at when the car is at warm idle and has idled for about 20 min also just because i figured i would need this
but if anyone has any hints or helps, i would appreciate it

Turn the key on. The needles should move. Then center them.

See if you can use diablo predator hand held. It will give you realtime info.

You can put the rpm needle back on at idle, but to do the mph I had to drive at 30 and set my cruise control, then put the needle on. My rpm and mph are spot on, and the other gauges you'll just have to go by your pictures.
