What threads on a Cortina axle?
Been trying to find some bolts to fit our prop to the flange on the 'tina rear axle but don't seem to be having much luck. At first glance
they look like M10s, but can't get a standard M10 in there, so thought maybe they were fine thread. Tried that, still no luck. Anyone got any
idea what they might be? Or are we just talking very dirty threads from spending the last 20 years on a scrap heap?! (we did try cleaning one by the
way)

Could they be imperial?

They are a fine thread, and yes I would have thought imperial

If it is a Mk3 cortina the bolts would be metric, probably M10x1

Not sure if it is a Mk3 but would have thought that it probably was. Tried both coarse and fine thread on M10 and it looked a slightly smaller, but
then perhaps the thread was just dirty! Will try again. Thanks for your help guys.

Well I think it's either mk4 or mk5 so there!
Fast Westie, are you saying that mk1 + 2 would have imperial and mk3, 4 + 5 metric? If so I seriously doubt that ours is a mk1 or 2.
Anyone know which ones had void bush suspension 'cause our axle has the hangers on top of the diff casing. If the answer to that is "mk4
and mk5" then that's what we've got.
So back to the original question then. 
Suppose we could just phone up our local Ford dealer and ask but that'd be too easy wouldn't it

Yes it would... you know as well as I do that if you haven't got the make, model, registration number, engine size and seat fabric colour then
they can't tell you anything about the car!

Mine is MK4 and had (until we cut them off) the suspension bush hangers on top.

All Cortinas from the Mk3 used metric parts (My Dad worked on the guaging for them).
Any Cortina axle with void bush mounts came from a Mk3, 4 or 5 (the only differences were in the bodywork). The axle is also a Salisbury design with a
rear loading diff.
Mk1 and Mk2 Cortinas used the English axle (similar to the Escort and Anglebox) with the front loading diff and used Imperial measurements.
I don't know the thread exactly (I haven't looked at one of these axles for over 20 years!) but would think that it is a M10x1. This is
not a fine M10 which I believe is M10x1.25. I think the Sierra diff uses the same threads. Your brake pipe connections will also be M10x1 so you could
try screwing an old one in.

Thanks for the info.
We'll try to clean the threads again and try an M10x1.
I'll post back once we know exactly what they are just in case it's useful to others.

Cortina flange thread
Get some Sierra bolts. That's what I did. Just one run to the scrapyard and you'll have the right thread and strength.
