We carry the PST 3.5" aluminum driveshafts, which come complete with 1350 U Joints, for $399.99. These driveshafts have a very high hp rating, check them out on my website. Bob

Denny's.

Well, you mods are pretty mild, so although Denny's is a great shaft, as well as the other one mentioned, they might be overkill for you application (read - heavier and more expensive).

Why do you need a new shaft ?

well the u-joint broke and i put a new one in, and now the driveshaft squeaks or something in the drivetrain. the reason i want a new one is i want to dump it at 4500rpms, will the stock one hold that kind of launch???

heres the pix of the u-joint

Well, for that kind of launch with a stick I would go with the 3.5" alum shaft, or if you are going to mod it more or spray it later, look at the Denny's or a CF shaft.

Look for a used LT1 Or LS1 steel driveshaft. I broke the aluminum one in half at the track and wont go back to aluminum. They can be found cheap.
