Need help quick...pilot bearing question

Im doing some dyno testing of a 03 4.8L truck motor. The dyno input shaft is about .59" OD which is the same as the older GM manual transmissions. As close as I could measure the ID of the crank is 1.063". Where can I find a pilot bearing/bushing that will work? Part numbers would be great!

thanks guys, i will post up my dyno results here when I am finished to try and help us conversion guys determine the best setups for our conversion projects.

Cant give you measurements and not sure if the 4.8 is the same but I can tell you this much. I had a new pilot bearing that I never used from a previous build ( sb350 crate with t56 ) and it fit the LS1 crank fine.

Looks like most manual trans GM cars since 1946 use Motormite/Dorman/Help part #14650 for the pilot bushing. Includes LSX, SBC, BBC, straight 6's, V6's, Iron Duke 4 cyls, etc.. you can look up all of the applications on dormanproducts.com.
