Hi,

A while ago I bought a pair of Cortina uprights of eBay for my Tiger Avon. I was told they were Mk 3/4/5. However, now that I try to fit them onto my ball joints, the holes in the uprights for the tapered bolts are too large.

Have I bought the wrong uprights? Are they Mk 1/2 Cortina instead? Or were there different flavours of the Mk 3/4/5 that had different (larger) sized holes? They look like the right uprights and the calipers look right, if a little rusty!

If anybody can help identify what is wrong I would be most grateful. Even more so if somebody knows of a simple solution.

Thanks.

Which ball joints are you using? If you use maxi type they wil fit ok. I think all uprights use the same taper.

Hi,

I'm using the ones provided by Tiger. I believe they are Fiat 127 and Ford Transit.

Find any one locall with a maxi ball joint to try in it. It will tell you if they have been modified or you have the wrong ball joints.

Sounds to me like they are tigers joints for the sierra uprights. They are smaller.

as far as I can remember the MK I-II used struts so can't be for those

Thanks for the advice/info.

Its been pointed out that I might have them upside down. I will check that tonight. If that is the problem I will be relieved. Fingers crossed.

Turns out it was me being a bit of a spanner. When these were tightened up they worked fine. I was not taking into account how much the rubber boot squashes up as the upright slides up the taper.
