Vixen / Tuscan rear upright flanges

[kabaman]

As far as I can tell, the four bolt flanges on the inside of the rear uprights are different depending upon whether they mate to a Vixen driveshaft (to TVR pumpkin diff) or a Tuscan (to Salisbury diff).

Does anyone know the original parts/source for both options?

Thanks,

I imagine Steve and Adrian have a more complete response, but my 2 penneth, for what its worth is this.

I had to replace one on my Vixen S1. The Vixen parts list lists this part as a TR4-6 gearbox to propshaft flange part number 58948. Its apparently discontinued according to Rimmers, but they do have some recon items in stock. When I ordered one it turned out to be a completely new item that looked v slightly different to the original. It needs a different seal, because the outer diamensions are slightly larger and it is also a few thou shallower and needs a washer to allow the castllated nut to clear the quill shaft splines. Cost about £30 I think.





Bottom picture shows the new version.

As yet, I haven't fitted the diff and drive shafts so I cant comment on whether this all works or not.

Thanks for the response. I now have some idea what I already have. The larger Tuscan ones are what I need next ;-)

Anyone out there know?

Thanks,

As far as I know, the upright flanges are all the same, and the inner flanges were changed to match the diff used. This could be wrong, it's what I remember ...

The diff options were Spitfire/Herald, TR6, and Salisbury.

The Vixen used flanges which were Triumph Saloon/TR6 but drilled to match the smaller Spitfire diff, and might have been machined a bit on the locating 'ring' (to match smaller diff) , not sure.

The TR6 diff doesn't need any flange changes, and I think the driveshafts are T2000 saloon ??

The salisbury used specially made flanges to adapt the diff to the driveshafts, as there was no UJ combination to match Jag originals to Triumph bits/shafts

The driveshafts are different lengths for each of the 3 diff options.

And I'm not sure there are different UJs for the driveshafts or not
