NB rear uprights on a NA6 ?

Postby PeterB » Sun Jul 17, 2011 11:33 pm

Hi all, I couldn't get a definitive answer by searching, so over to the experts.

Can NB rear uprights be used on a NA6, still using NA6 discs and calipers ? I am looking at doing a diff upgrade to a stronger NB one and will have the choice using of the NB uprights that come with the diff conversion, or swapping back to my NA uprights.

The brake backing plate is larger, but are the suspension locating points and caliper holes in the same location and the same size - they look the same ?

Any advice appreciated thanks

Mainly because the uprights/hubs are still on the NB driveshafts (and seem in good condition) and are being a major pain to separate, so fitting the low km NB ones will save me a lot of hassle if they are a bolt on fit.
The previous owner has already smacked them with a hammer and damaged the ends (not the thread) so the drive shaft needs dressing up already, so the less I have to do to them the better.

A bonus will be that the larger backing plates will suit a big brake upgrade if I go that way later on.

Thanks muchly.

Carco have managed to separate the NB hubs from the NB driveshaft, so I fitted with the NA hubs, but at least now I have a spare set of hubs that will fit both my NA and NB.

thanks everyone
