Oh dear, if you don't have them your in trouble.
Ford don't stock them anymore and nobody else makes them. I think they are unf but you need screws, and there are only bolts available with the
correct thread.
Get yourself down to the scrap yard and take some off a Sierra. QUICK!!

I think in general there are two pitches with UNF, 12 Teeth Per Inch (TPI) and 16 TPI.
Even if you have UNF they still might not be correct, thank goodness we are now nearly all metric when you add in BSF etc .... it becomes a
minefield

or the other thing you could do is buy some bolts of the correct standard new, there must be somewhere local should stock the right spec in metric

Namrick's table of UNF tpi spanner sized etc is here:
http://www.namrick.co.uk/boltspec.asp
They stock set screws in UNF in high tensile S grades (equivalent to 8.8)

But without knowing the size/length I don't know if they have what you need.

If you can't find any of the old bolts, just drill and tap some new ones?

Hi they are deinetly metric and NOT unf.
They are the same thread as the cvh/zetec flywheel bolts.
Many people mistakingly fit unf and f##k up the thread meanig the flange is not safe to use again.

The front loader engish is definatley UNF bolts though.
Not that that helps in any way, but I feel better for sharing it.
Thanks,

are they different to front loading (english axle) then? ???
for sure they are fine pitch, I would guess UNF.
if you know the dia/pitch, I can try my local fastenere place.
I don't think ou can get a nut on the back sou you would need to tap with anotehr fine as the flange is not the thick.
