1970 340 clutch release bearing part number?

[Airfix]

Just picked up a N1054 SKF release bearing, it's different from the one I removed, the inside diameter is too small but the parts listing at the auto parts store says it's correct.
Anybody else run into this problem?
If you any part numbers please post.
Thanks.

hi, what trans input spline is the transmission? the 18 spline is larger than the 23 spline. the part number you have is for a 23 spline trans. maybe wrong bearing in box??

The sleeve and bearing assembly that works in the 23 spline is SKF N1463.
