[Fot] re TR4-6 steering arm differences

[Enquiries Road & Track]

thanks to the various people who emailed me privately about this

i have confirmed the steering link arms, top wishbone, and steering
rack ends all changed dimensions when they moved to 3 degree caster.
The factory TR4A book gives dimensioned drawings of the parts, early &
late, so I can now identify them

what I still cant figure out however, is why there is a change between
wire & steel wheeled cars as suggested by parts books,  and the repair
manuals make no mention of this

the steering arms for zero & 3 degree caster are quite different to
look at , but i dont have any bump steer data as yet to work out the
improvements
