Maybe I misunderstood but was under the impression the aluminum factory driveshafts would bolt tight up to my car. They are not quite the same length and the aluminum one is much larger around. I could not get it to slip over the spline of my lt1 T56. Is this not for this? I hope I didn't waste 150 bucks.

 

Should work just fine, 4l60E and t56 have the same output shaft spline.

 

it'll work. i swapped in an aluminum one on my '96 Z28 without issues

 

Maybe I wasn't forceful enough. I will grease up the splines and try again. I was thinking of swapping the yokes but if it will work I will get it in.

Thanks guys.
