Vixen front upright source?
Discussion
Hmmm
The Standard10/ early Herald drum brake vertical has a metal plate added to hold the caliper (as used on my Clubmans car)and are rare ... if you need a pair look for a Standard 10 being broken and reuse your caliper brackets.
The slightly later Herald/Spitfire vertical (As used on my Fairthorpe) is far more common and I believe a direct replacement ? Comments welcome.
The Vitesse/GT6 I believe is stronger but still uses a bronze trunion and the final upright in the family is the Caterham one that does away with the trunion (as used on my Formula Ford ..) but would need the bottom wishbone reworking to fit ...
I think verticals have a habit of rusting just above the bronze trunion if the rubber seal isn't regularly greased causing failure - I think buying second hand is therefore unwise without crack testing ??

Someone in our midst let me in on this little gem.

Could you elaborate on this please ??
I thought you could change the upright if you retained the Standard 10 steering arm.
The Fairthorpe is actually a Standard 10 bronze trunnion based suspension which is a pig so I converted to early Spitfire uprights and retained the old steering arms.
Is there something subtle I could have missed ... I have to admit the conversion was done 20 years ago and the car seems to point roughly in the right direction.

The Herald and GT6 uprights have slightly different size tapers where the stub axle fits in... the TR6 stub axle (as used in the Vixens) won't fit into the GT6 upright correctly. Found that out once when I got a GT6 upright by mistake.... And anyway, it doesn't look that much beefier to be honest, they use the same trunnions and thread, and that's where most of the force will resolve ?
'M' Series went to all TR6 front suspension arms and uprights
Arguments ?

if you,ve a specific requirement then the answer is that you can mix and match certain parts....You have to be very very carefull though since there are different stubs, tapers, hubs and bearings to consider.
The std set up in good condition works perfectly well with most 4 cylinder engines for all applications other than all out racing!!

The principal reason for changing is to do with pad knockback when racing. The GT6 stub has a thicker outer end and therefore less flex on the outer end of the stub. the inner bearings are the same. To fit the hub to a GT6 outer involves machining for a new bearing housing on the outer. Doubtless you can also possibly source a ready machined alloy hub. It can be done but it is a bit of a slaver on and unless you are using the car for all out competition probably un necessary.
