    Best bet is to just install everything and just measure your belt routing with a string or piece of wire. Then just take the old belt to the part store and tell them you want one the same just shorter.

    You might not need to change the belt. The lower pully is smaller but the other ones are bigger. It kinda balances out.

    wrap the tape measure around the pulleys as you would a belt. and it will give you length in inches.

    Well, that's VERY close to a 93 Cobra Crank pulley. If you can find a belt listing for the 93 Cobra, that may work. Keep in mind if the smog pump has been removed, it will be a total guessing game.


    $hit, I wasn't supposed to help! :upyours:

    If all you are doing is add under drives you should be able to use the same belt. The tensioner should take the slack out. There isn't that big of a difference in the pulley size.

    i think he's just replacing the crank pulley. never can tell which personality is talking in sentence fragments.

    also, if you can't fix that dipstick, you sure as hell ain't gonna get that crank pulley off there.

    Guess the fact that a wrench is NOT involved when it comes to the dip stick must be confusing.

    You guys crack me up. SCS has some of the best entertainment.

    Jared, I'm sure your a good guy, but sometimes I think you should drive a ricer with a coffee can and a dragster wing on the back.
