Not correct pilot bearing for Gen 1 SBC

Comments about National Ball Bearing:

This was in the list of pilot bearings/bushings that would fit my Gen1 SBC (2 pc RMS) in my 86 Z28- all parts selected were made on an 85 Z28 Vin G on Advance's website. It did not fit- close, but loose. Went with the bushing included in the clutch kit instead so I can take this back. It seems to be a nice bearing otherwise, too bad it was a wrong match.
