Nope. They are 31 spline, MN-FN are 28. If you're looking for replacements check rock auto or your nearest autoparts store.

if you are just looking for something cheap, I have a pair of halfshafts from a 93 V8 (5.0) car I'm happy to sell off.

The only catch is that they are for a car w/o ABS as there is no ABS ring on the inner end of the shafts.
PM me if interested.

FYI, those can be pulled from another pair of halfshafts and installed if necessary. I've pulled them from stock halfshafts and installed them on DSS Level 2's in the past.

Thanks everyone!! I have a buddy that converted his 03 a long time ago and those were sitting in his garage and said I could have them and they only had 10k miles so thought I would ask. I dont need them but have been talking about ripping all the stuff off my cobra and making the cougar a sleeper. I bought it to drive my kid to school and got a smoking deal on it because an old couple was moving to Florida but now I see the potential of this car and would love to see it at 500hp..

Yikes those shafts are 1600 bucks! http://www.driveshaftshop.com/domest...rd/thunderbird

Is there anything that splits the difference between $1600 and Cardone?

...and those are the cheap ones. The better ones are high-alloy 300M steel.

There's nothing in between that I know of.

I've broke four half shafts, on launch on a sticky track.
Foot braking.

The stockers break at the end of the splines on the outer stub.
4000 stall, 324hp and torque, 3:73 gears.
All on the right side.
Two were with Traction Locks and two were with a mini spool.

31 splines are not necessary, larger axle shafts are not necessary,
Larger axle joints are not necessary.

Larger outer axle stub is all the DSS axles provide.
They are worth it, for my application.


Now its a 4500 stall and 4:56 gears.

I think what I did was self inflicted. When I rebuilt the diff I swapped out one of the steels for one of the old fibers which made a nice tight locker for the last 15,000 street miles. Over the weekend I took it to a road course and I think what happened is it got hot enough that those clutch packs basically seized up and wouldn't let the outside wheel turn faster on the corners. I broke the inside drivers side CV joint.

So now I'm not sure what to do to fix it. I'm thinking the cardone shaft was fine and I just need to put the clutch packs back to the way Ford had them. I thought about putting a truetrac torsen in it but not sure it's really needed.

Thoughts?

If you're doing road courses, I'd go with a geared instead of clutch-based diff.
