lower balljoint alternatives
I intend to use Sierra Cosworth front uprights on my Indy, which means a slight redesign of the lower wishbones. Now I'm looking for suitable
balljoints. The hole diameter is 17 mm, and the thickness of the part is 26 mm.
Any suggestions?

do you mean 4X4 front hubs? if its the same taper as normal sierra hubs, the astra ball joint will work. You can still get it drilled up to a
different taper if you want.

Yep the 4x4 has the heavy duty type with clamp not tapered fitting.
Take a look here http://www.partsforsaabs.com/default.php?cPath=2_78
Also have a look at Montego ones not sure the exact dimensions but quite chunky -- they come in left and right angles to allow for castor.
Also Astra 98 onward and Fiesta 95 on (2 types with an without PAS) although listed by QH these might be hard to get because usually as cheap to buy
wishbones.

Mave,
How come you want to use this upright? If it's the callipers you're after I believe they can be fitted to standard uprights.
HTH,
James

I'm talking about the 2wd Cossie uprights. I'll try to update my website this evening, to show the difference.
@ James: yes, the big Cossie brakes can be used on the standard uprights: but it means taking off material from uprights, as well as calipers. (a
total of 5 mm in total!) Using the Cosworth uprights seems the safer alternative.....
Does anyone know what kind of lower balljoint Formula 27 uses?

Looks like Transit drag link, the top I am pretty sure is Fiat/Lada .

I'm sure someone recently said the Robin Hood boys use standard uprights with these callipers. Presumably they use a spacer plate.
Have you considered using some Willwood brakes instead? Bit pricey I know but they weigh very little and you could sell your Cossie upright/callipers
to off-set the cost. I just wouldn't want the added unsprung weight- that's all!

BTW, anyone knows the weight of the Cortina Mk3 (I think it's what is called "standard" and Sierra uprights?

I have tried using these caombinations of brakes and uprights and you do have to use the 2wd cossie uprights with the 2wd cossie brakes (the 4 pot
ones). The 4x4 cossie calipers are different (1pot sliding) and will fit the other uprights with spacers but the 2wd are offset the
"wrong" way and as was said, you have to machine away the already rather thin caliper ears on the upright. Also the cossie upright is
threaded for the caliper mount, the standard upright is unthreaded and the caliper frame is threaded instead. phew...(used the 2wd uprights/brakes on
my RWD Pug 205 rally car)

NS Dev is right. And I might add that the lower hole also has a bolt to clamp the balljoint (and the bolt actually partially crosses the balljoint!).
Sooooooo, any suggestions?!?!?!?
Help?

Ahhh, even more tricky!! The 3 door 2wd cossie certainly didn't use the pinchbolt, just a normal taper fitting, and I think the 2wd sapphire
cossies used this too?? I thought it was only the 4wd that used the pinchbolt (used cos you couldn't get a "top nut" on the taper
with the front driveshaft in the way!!) In any case,, worth comparing to a Vauxhall Nova bottom joint, as this comes off the arm easily and uses a
pinchbolt. Also the mk 5 escort and the fiesta's with wishbones at the front instead of TCA's, on these it is quite easy to remove the
lower balljoint (they are normally rivetted on, but the rivets grind off, and you can get replacement kits for just replacing the balljoint instead of
the whole arm) worth a try, dunno if they'll fit but you know Ford!!!

I'm still looking for suitable balljoints.
Does anyone know which balljoints the Rush Quadra uses? If it has roughly the same uprights, with only a different hub, then I might be ably to use
the same.
@britishtrident: do you have any dimensions of the Saab balljoints in your URL?
