    if you want to get to this stage



    then you have to take the rear circuit baord off. Only about 7 screws then push out from the dial side

    oh, and undo the lil white clips, they can be a pin but you'll get there in the end!

    Chances are they won't read right if you just swap the cards/needles over - mine didn't when I tried.

    no. Neither the zaf a or the astra g require you too take the wheel off. Astra you have to take them out through the steering wheel and zaf a is very easy, apart from getting the dash off in the 1st place! and its 10x's harder getting it back on!

    Best way to get the needles level is start the car, ignition only, with the clocks in place but without the plastic cover on the front, then the clocks will set to there correct position. the turn it off and wait a second. then put them all the needles at the starting position then they should be level and correct. check by turning the key again, if succesful then put the plastic cover on and the dash back together. Dont put the needles on too tight as mine are sticking at the moment! Speedo one jumps and hates dropping. Need to sort mine asap! LOL

    IIRC the black faced and white faced clocks use a different PCB. The reason for this is because one of them has the zero calibration point lower than the other. So if you swap the dial mat over the needle will actually read zero but the car thinks it's doing say 10mph. Now this doesn't sound a problem right? but the fact is that as the car speeds up the amount of needle movement decreases, look at the gaps between the speeds higher up, smaller right? so when your doing 30mph you may be showing 25mph, this difference increases the faster you go. You stand a fair chance of being caught speeding even though you think your going at the right speed.
