Thanks all, now there are 2 replies that state that a small amount of
movement is normal so I am beginning to feel more confident. 



Rear tire wear (and front tire wear, for that matter, as the amount of play
is roughly the same front and back) is uniform. 



The amount of play is really very little – I guess my question was if there
should be zero play (this is not the case) or a small amount. At this point,
I’ll probably press on and ask the experts in Le Mans in a couple of months!



(Note to Le Mans Classic attendeees – if I am not there because all four
wheels fell off due to bearing failure, carry on without me!!)

Charlie, I don't know if your #1 GT5-S is different than later ones, but the
'87 I worked on (for the same reason) had a std ball bearing outboard and a
wide straight roller bearing inboard, with the upright bored out to fit the
larger OD inner bearing. The spacer between the two was shorter than the
early cars with two ball bearings, and the required torque of the stub-axle
nut was the same as with early cars (350-450 ft-lbs). Brand new bearings
installed in the '87 on aftermarket axles had virtually the same 'play' as
the stock parts, at significant expense.

GT5-S rears routinely fail open track race inspections if they're done by
inspectors not familiar with the design of this model; the wide roller
bearing has significant play while laying on a bench and installing the
bearing in the upright on tight-fitting axles does not eliminate all of it.
So it's a judgement call as to whether the play felt is from a loose-fitting
axle or "normal" straight-roller bearing play. I'd carefully check your rear
tire wear and if that's OK across the tread, your rear play is probably OK.
Good  Luck- J DeRyke
