I would honestly just have the shop that is gonna balance it put new u-joints in if you are not equipped for it. When I had a DS made for my 460 car it was only $10-15 to have them do it, wasn't even worth my time.
Also check to see how much it will cost you to get it balanced and for the u-joints as it may be just a little more to get an aluminum DS. I think you will be in the $70 area for your DS and $150 for a new one, something to consider.

Do you own a Torch Red FRC and tremble every time you drive under I75 on Hwy 60 and look in your rearview mirror? If so you are suffering from what is known as Cobraphobia.
