I agree, they're all the same.  And I've got lots of them, but you'd probably
prefer to find one closer to home.

I've never seen an engine that needed a packing piece.  But all it is, is an
extra gasket (or 2 or 3) under the pedestal.  By now, I think it's safe to
assume that they are all worn enough to not need any extra clearance here.

That's what this procedure is about.

Probably not necessary, but I'd smear a little Hylomar on there, just to be
sure.

The pedestal is cast iron rather than steel, and cast iron is kind of brittle.
As I recall, the manual procedure is to add a known spacer to the gear, then
install the pedestal (which will sit on the gear instead of on the block) and
measure how far away from the block it stands.  Just put the bolts in
finger-tight while you're doing that.  If the clearance isn't equal all the way
around, loosen the bolt on the narrow side before tightening the bolt on the
wide side ... still just finger-tight.
