    I have mine rebuilt...
    I take it to the shop, have them tear it down and then I bring the paintable parts home to be...glass beaded and painted. then I take the parts back to be reassembled...:yup:

    I will have to try finding a shop around here that can do that too for a reasonable price too...did find a place that has 2 alternators in stock both USA industries both for 120 Euro's:

    7058 - w/ Ford 40-65 Amp
    7072 - w/ Opt Ford 70 Amp

    If i have no luck finding a place i might just order one from this place or get it from RockAuto, still cheaper but will take longer to get here.

    Which of the two would be best? does it make a difference at all?

    well i found a place that can revise my alternator, but quite costly, between 120-150 euro's...just as much as a new one, so not to sure what i should do now, revise it, or just get a new one...what you guys think?

    The more output, the better. Generally a local shop rebuild is far superior to one from a big rebuilder. 20 years ago this was always true, many rebuilders would clean em up and rebox em and send em right back out the door. It was common to buy a rebuilt alternator (and starter) only to find it was no better than the one you were replacing. This is why I usually buy a new unit now than take a chance on a rebuilt unit, that and the fact that I can afford to buy new now, so I don't have the same experience with rebuilds now that I used to. It's your money, your call. If the guy doing the rebuild is reputable, and stands by his work, by all means go that route if you can afford it. It's also a plus if he knows his stuff in dealing with the electrical system on your car.

    I decided to get a new one, so i tried to take out the alternator but it seems that is not going to be so easy...the bolt on the top of the alternator is completely stuck..i sprayed it in with some oil and letting it sit overnight hoping it will go tomorrow!

    I don't have any idea what oils you have there, but I would try an oil specifically for corrosion penetration. If you can't find that, try a gun bore cleaner such as " Hoppe's #9 " It may take awhile to soak through! That long bolt can be a booger! :cry:

    Get a propane torch and heat the alternator body where the bolt passes thru it, you'll wait a long long time before getting any sort of penetrating oil to soak thru the corrosion to free the bolt. Once you get the bolt to turn, it'll come out as far as the threads will push it, then you'll need to drive it the rest of the way out. The heat will do more than oil will.

    Impact gun will get it out or it will die trying.
