    Or is this too big to fit in the tunnel and clear everything?

    Getting estimates on how much it will cost to cut it down and put the yokes on...

    Should I use my current shaft or get a donor shaft to cut up?

    A 3.75" diameter shaft will fit so I don't see how an extra .25" would make a big difference. Unless you have alot of flex in the tranny mount.....

    Current shaft is stock. Bigger than the one I saw on a 70, but still stock steel. I am not sure what goes into making one fit, and if they can use the steel yokes on an aluminum shaft...:huh:

    The shaft in my car was built for my FOX body mustang (exact fit in my Comet) I just took a old steel 3" F150 shaft and had it shortened to fit.Cost me about $150 bux.

    Derek, was that an aluminum shaft?

    Can they weld my steel yokes onto an aluminum shaft, or will I need to find the right sized aluminum ones? I may just give it to the shop and tell them to do what they have to do, as long as it doesn't cost me an arm and a leg...:rolleyes:

    If it does, I will put it in the attic and wait til I pay off some of my debts, and just have the stock one balanced.

    Ditto!! The 79-2004 Stang driveshafts are the same length (plus or minus less than an inch) as the Mav/Comet shafts. I just scored a used one from a 2000-something Stang off ebay. The shaft that came with mine was 45.5" ctr to ctr of the U joints, the one I just bought is 45.75" Ford Racing lists an aluminum shaft in their catalog (45.5")

    Cool!!! So if this one doesn't work out, there are plenty to be found in the junk yards...

    i have a aluminum driveshaft that is wither 3.75 or 4 inch big and fits no problem. It is from a police car crown vic 2003 to current that i had cut down and made to fit in my car. It cost me about 175 to get it done.

    I had a brand new one made by The DriveLine Shop, $200 shipped to my door. All new materials including u-joints and a new slip joint for the T5. Dynamically balanced, too. Gotta be better the messing with someone else's 20 year old junk.

    No that was a steel shaft i had built.I dont really care for old aluminum shafts they tend to develope problems such as end yokes splitting and stretching and have seen some break as Frank stated
    And no you cant use steel end yokes on a aluminum shaft they have to be welded on.

    If all else fails, I can at least recycle this 4 lbs of solid aluminum...

    I should be able to get something made out of it...

    There is a very slight difference in length between the Fox body shafts and SN-95 shafts. The SN-95 shafts are longer by about a half inch and are bigger around then Fox body shafts. I know because my dad's '95 Mustang is lowered 1 1/2 inches, and the stock drive shaft used to rub over bumps. I put a drive shaft from a '92 GT in the '95, and the smaller diameter cured the rubbing problem.

    Is that for an aluminum shaft?
