size of thread for sump guard nuts on sub-frame

[Jersey Moke]

Hi

Can anyone tell me what size bolts and thread I need to fit the sump guard onto the font sub-frame nuts of my Aussie Moke ?

Thanks

9/16ths

That's the same thread as your wheel nut studs and cylinder head studs and nuts

9/16ths

For the rest of the world* that would be 3/8"

To clarify further,
3/8" UNF is the thread size (and what you ask for at the bolt shop....don't buy UNC bolts)
9/16" is the socket size you need to undo them.
I can't remember the length, probably about 1-1/4" to 1-1/2". You will also need a nice big flat washer and a spring washer for each bolt.

and its UNF not UNC ...as I once made the mistake of jamming in there.

The previous owner of my Moke made that mistake as well but still managed to repeat it over and over again

In my case I was away from home and bought a sumpguard. The easiest way to get it home was to bolt it on. When I went to fit a unf bolt it didn't thread in smoothly because the hole was full of grit. I just assumed that it was UNC instead.

Since then I've learned what a total pain they are. You can guarantee that every nut, bolt or spanner you drop will be stuck in a layer of oily sludge on top of the stupid thing. I've got two of them jammed into the furthest corner of the garage.
