[Healeys] Front wheel bearing spacers. New blog post.

[Michael MacLean]

I recently installed new hubs and bearing kits for my BN2 build.  Two
things.  There were spacers (original to the car as far as i can tell) and
the lateral clearance was supposed to be "0" without tightening enought to
cause any drag.  A lot of experimenting with shims.  So what's the
difference with my MGB GT that requires a few thousands of lateral movement?
