What exactly are the benefits with an aluminum driveshaft?? i really havent looked into them much.
To 19blkcbra99: Take a look at the link below for a possible 99 cobra driveshaft. The difference between yours and an 01 is that the T-45 has a 28 spline yoke and the T-3560 has a 31 spline yoke.

To 01MGSVT: Take a look at the link above for a description of the advantage of using an aluminum driveshaft. Also, do a search on "driveshaft" or "aluminum". There are a couple good threads on the subject.
Thanks for the helpful info. my car is not a 600 hp monster so an off the shelf frpp DS should be plenty strong for me.
Stock length DS is 44.5 center to center so I dont see how you can get an extra inch in there with the FRPP driveshaft. I have maybe an 1/8th of play in mine.
I know this has been beat to death and I personally know some have had success but the "J" driveshaft purchased last week does NOT fit my 2001 Cobra convertible (3650 and IRS). I am at least 0.5" (more likely 1") too long. I'm not saying others haven't had success but in my case it does not fit. Off to get it cut!
