meiermat,
Thank you very much for your input ; my gm parts guy had contacted me earlier today stated to me that yes there is a "sleeve" as he put it and believes its actually a roller bearing but not sure because he needed to order it. ( by the way he used my vin # to get the part ) Well I told him to order it and I will have it tomorrow.

I did go to another dealer on sat. and the parts guy there could not help me but said he will run this by some one with more experience on Monday. he also called me this morning and informed me that there is no pilot bearing of any kind (they did not have my vin # )

Any how tomorrow will tell and if it fits its going in. I just dont understand why it was not there in the first place . I will keep you all posted and let you know how i it plays out
Thanks again
Bob
