well i need to take off the needles to take off the gauges, so how do i do it ?

Needle tracks on your arms? Just wear long-sleeves!

I say you need some help buddy... The first step is admiting you have a problem, then remove the people from your life that have the same addiction.

Then the healing process must begin... It will take a long time, and a lot of work, but soon, you'll be a contributing member of society.

... Shit what were we talking about?

Haha, just messing.

Just experiment with it... Cant be that hard.

i just pull them stright out ? the needle alone or the black center piece too ?

on most cars its just the needle. you can use a fork and kind of pry/pull them off straight as an arrow. but this is for most cars, and everyone knows the 300zx is not like most cars. so you might need to verify with someone that is all it takes.

I think it you'd be better of selling me the car cheap and get one that has what ever is is your trying to do already done to it. But if you insist on keeping your car then I suggest you follow K3's suggestion.

also, be sure you mark the needles. most people will tell you to fully warm the car up to get the proper setting for the heat guage. then mark where everything was. then before you put the needles back on make sure you warm up the car again, then just snap all the needles back on. you will probably have to do the tach while the car is off to get a good placement. take your time and do it right the first time...i did it on my old car and i messed up the gas guage so i had a little less fuel then the guage said. so i had to take it all back apart and redo it when i figured it out.
