    Ok so I'm getting the tranny swapped but when I was trying to match up my pressure plate, I could only get three holes to line up instead of six could I get away with that?
    I bought the flywheel from this Site from a fellow maverick buddy told me to get one from http://www.kajunjon.com/flywheel_clutchkits.htm . I try calling them but no answer on how it goes on. This engine is the older sty not roller so I can't just get a roller flywheel and toss it on. Can anybody give me some help on what I'm doing wrong?? maybe it's the flywheel that's messed up Idk. I matched my flywheel with a roller one and it's the right diameter but the holes don't match up I can get six on the stock roller flywheel and 3 on my flywheel. Please help!!

    You need all the bolts :naughty:
    Which bolts? Flywheel to crankshaft or pressure plate to flywheel?

    Clutches exert enormous force so you need the six bolts.....I would say more than likely you have the wrong pressure plate and disc....I think there are 10.5 and 11" for small block Fords, maybe even smaller for 6 cylinder engines....I believe the correct disc should be the 10.5".....Measure the disc you have....Or you could have a 11" flywheel, in which case i don't think the bellhousing will fit over it

    thats what i thought i got the wrong pressure plate too, i work at a auto parts store and i ordered another clutch kit too and still it didnt wanna fit ..BUT when i try to line it up with holes it feels like the pressure plate is a bit too big for the flywheel is it suppose to be like that??


    this is what it says it is on the site....

    BRAND NEW! 10 1/2 inch Mustang Fairlane Flywheel: 157-tooth, for EXTERNALLY balanced small block motors. This is a
    28-ounce balance wheel. Weight: 19 lbs. Diameter: 13 1/4 inches

    When you hold the pressure plate flat against the flywheel, the mounting flanges {where the 6 bolt holes are} does not fit flat against the wheel until the bolts are tightened up....This should be done in steps....In other words don't tighten one bolt all the way down and then another one all the one down....Do one maybe 3 turns after it feels like there's pressure on it, then move to one on the opposite side and tighten that one maybe 3 turns after it feels like there's pressure on it, and so on ...You are compressing the springs on the pressure plate so it has to go evenly.....Not a bad idea to put Loc-tite or at least lock washers on the bolt threads and they should be torqued to i believe 35 ft. lbs...A lot of flywheels have a bunch of holes in them for different applications..Make sure you're trying to fit the pressure plate to the right holes

    Ok so I can match it up to the first three holes tighten them evenly and it'll slowly compress it to fit to the other holes?

    As long as it's the three opposing holes....Like a triangle

    I have to ask, was the flywheel for a diaphram style clutch or for the 3 finger ford(borg and beck) style clutch.
    Because with the information you have got(and what is given on that website) I think you have the wrong flywheel.:cry:

    The flywheel for the 3 finger clutches is SAE... the diaphram clutch flywheels are metric. That means the bolts and the alignment pins are metric diamaters, they are close too the standars of the original flywheels but they dont quite fit. An easy way to tell is do you have holes for the alignment pins that the clutch needs too align the pressure plate with the flywheel? And yes you have to have the alignment pins otherwise the clutch will wear funny, they come in your pressure plate bolt kit
    http://www.americanmuscle.com/frpp-...frpp-pressureplate-bolt-kit-8698-1986-Foxbody
    But sad to say looking at the picture of the flywheel on their website that is for the 3 finger style.

    Soo my suggestion is get ahold of the company that sold you the flywheel and make sure you are putting the right clutch on it before you screw up your pressure plate trying to bolt everything in place:thumbs2:

    I see.. that works, but back too my question is it a conversion flywheel that is setup for a diaphram clutch or is it a stock replacement flywheel that wont work with a diaphram clutch?(and T5 bellhousing)

    Any of these flywheels will work..

    Do you plan to run a lightweight flywheel on a street car? If so, it won't be fun. You will be down shifting and riding the clutch everytime you turn around.

    As the others have said, you've got the wrong pressure plate to fit your flywheel. The diaphram pressure plates use a different bolt pattern than the older borg & beck, or long style pressure plates. 3 bolts ain't gonna cut it.

    ive had two street cars with aluminum flywheels. the were great on the street. the trick is to have enough gear in the rear. i had 3.89s. in my maverick and 4.10s in my mustang.
    i also put an aluminum flywheel in mashori's car. his car has 4.10s. when he did the silver state classic we swapped in 3.00s. he didnt have any problems with having to drag the clutch.
    i highly recommend putting in an aluminum flywheel on any performance car. there is a noticeable seat of the pants gain when you switch.
