Lakewood scatter shields

was wondering if anyone ever run into this problem with lakewood bell housings? I put 1 on my Muncie and bolted it up to my 327 with a new centerforce clutch,plate and bearing,well heres the kicker car running put into gear car starts rolling but you can hear the disc spinning and not engaging all the way? Lake wood says you need a longer bearing? tried to adjust it but with no help,getting ready to throw the original back on and be done with it,I have heard this happen to others and they pretty much did the same.any input would be helpful.

Regards,
Terry
