Bolt on drive shafts
I'm building a Tiger Avon and was planning on using the rear disc brakes from a sierra.
I now have the sierra in question, but after speaking to Tiger, they say you can't use this set up as the bolt on drive shafts don't fit
through the holes in the uprights and they are the only uprights for the Avon.
Has anyone come across this and does anyone know the diameter of the drive shaft ends.
I was planning on breaking the sierra, but if I can't use the rear disc/diff set up I don't think it's worth it. It has an MT75 box
2.0 DOHC engine which I'm not going to use, so I'll only be using the steering column, handbrake lever and V5.
Cheers in advance,
Neil

I had this problem when i changed over from push in shafts to lobro for my lsd diff
they are a bigger 100mm dia not sure what push in shafts are about 80mm i think.
so i had to have new uprights made
why don't you use push in shafts and drum to disc adaptor plates
ETA this of course was my mnr

I thought that the Latest Avon uprights were now able to take bolt-0n driveshafts?
Anyway, I fitted LSD, rear discs and bolt-on shafts to my Avon but as it was an early kit (2000) I had to modify the uprights by removing the lip on
the inside and swap them to the opposite side so calipers were mounted rearmost (to prevent the handbrake cable fouling ) I also had the ABS teeth
machined off the outer lobro joints and elongated the holes in the hub carriers to align with mounting holes on uprights as they are a different
spacing to drum type.
So all in all, a lot of work. If I wasn't fitting an LSD, think I would either stick with drums or get the adaptor plates to fit discs to the
push-in shaft set-up.
Have a search in 'Avon' section and there are also one or two pics in my archive which may help.

Hi Neil, I had the same problem and I can turn the shafts down to make them fit.
Its the ABS ring that fouls the upright, I just stuck the stub shafts in the lathe to make them fit.
Get them off, bring them over and we should be able to sort it.

Andrew, when you say remove the lip from the upright, what lip on the upright are you refering to? Also were the drive shafts too long or were they
ok.
Steve, I'll take you up on that offer but it'll be after october as I'm away to Florida and have no time to start before then. BTW
did you go to stafford? I was there in the tin top but couldn't see your car!!

No problem Neil, just giz a shout when you get back,
No didnt go to Stafford, was put off by the weather, my class 1 training and some work over the weekend... in that order.
After reading some of the comments, on here, and other forums I'm quite pleased I didn't go!

Tiger have known about this limitation for ages and even talked of opening up the hole to allow the use of bolt on shafts, surprise surprise they
havent bothered probably too busy launching another car that wont sell!

Its the cicular lip on the inside of the upright - that surrounds the hole through which the driveshaft stub shaft passes. If you don't grind it
away til its almost flush, the stub shaft won't sit fully home and will foul on it.
