Hi John -
I have the later style Atlantic Saloon, the track rod joints are male
threaded (cross tube female)... so I guess they are the same as on a later
BN1.
The A90 rear brakes have hydraulic brakes just like my early BN1... so can I
assume the rear brake cylinders are the same eventhough the part numbers are
different (7H4464 on the A90 vs. 7H4597 on the BN1 & A70)???? The answer to
this question can save me alot of money!
Thanks!
Alan
'52 A90
'53 BN1
