I have found a few places that have these, but they are all listed for the GT model. Is there any place I can get an aluminum driveshaft for my 99 cobra?
Thanks.

Check this one out... I bought one for my 97 a few months ago... I will say that there really isn't a great difference in weight from stock. The Yoke is lighter, but the shaft itself is so negligibly lighter that you can't tell the difference when picking it up (I will say that it looks lighter due to the stock one having a little rust tone to it)... I am sure that the aluminum driveshaft is stronger... but how much HP or torque would it take to break the original? I don't think that the mod was worth it... I think that you would do better in getting some lighter wheels, if you are looking to get more of the horses to the road by reducing your rotational mass.

So here is what I have been able to figure out over the weekend.
Any aluminum driveshaft build for a 99 GT will not fit on a 99 Cobra. Because of the different transmissions that come in the Cobra's, the GT driveshaft is one inch longer than the Cobra one. A person could buy one made for a GT and have a machine shop cut an inch off the end. That may end up costing less than having one custom made.
Also, having driveshaft vibration is possible following a gear swap resulting in a higher ratio. I had 4.10's put in and I have the vibration. This is caused by a change in rotational force. The driveshaft is factory balanced for specific circumstances. When you start playing with things, it throws off the system.
I found out that I can either install a balanced aluminum driveshaft, or have my OEM one machined and balanced (much cheaper).
I will let you know how it turns out.

yeayea0

buy a GT one and have it cut...most shops won't mind it as it doesn't take long at all and is quite easy. IMO its your best option, custom anything costs $$$

When i bought my cobra from the originol owner, he had done lots of things to it. For instance 3:73 gear, cai, and pullies. I had no idea that the driveshaft was replaced with a aluminum one until i changed the clutch. Then i also noticed that he had spliced wires coming off of the tranny into a speed cal. There was also sub-frame connectors to add. I was like WTF, all of this **** i didnt even know about.
