AH BN1 / A90 Atlantic Crossover help

["Alan Seigrist Blue 100" <healey.nut@gmail.com>]

Hi all -

I know this will probably be a weird one for the most of you, but would any
of you know if:

1) The track rod ends (steering ball joints) on a standard BN1 are the same
as on my '52 A90 Atlantic Sports Saloon?

2) Are the rear brake cylinders the same (they look the same), or do they
have a different diameter?

Sorry to ask but my BN1 and A90 are not in the same city so I can't realy
compare them.  Just freshening the car up for HK MOT and I need to sort some
of this out.

Thanks,
Alan
