Doing the Alt Overdrive Pulley that came w the Blackbear Kit on my 03 SS Silverado 6.0L

I got the Stock alt. pulley off and set it on the bench to check n make sure the rips line up, Looks like the Blackbear one is going to sit out towards the front of the truck a full rip width from my stock one...

Any one got any input on this, one thought I had is if I might have got a 5.3l pulley but I wouldnt think there would be a difference. Thx

 

5.3 pulley is the same, and you really didnt need the pulley...

 

Ya i figure i might as well if I got it apart just in case plus trucks got 130k on it alt prob not far from puking lol

 

Prb Solved Blackbear has been out of the shop for tuning session So I chucked her up in lathe and sized her up
