wrong mounting bolts to fix for Torq-A-Verter to Honda clone eng

I don't know if others have had this issue, but my Comet TAV2-30
Torq-A-Verter has arrived with a bag of fixings but the bolts do
not fit the mounting holes on my clone engine.
I am assuming this is because my engine is metric and the TAV
imperial? That said, my engine (Lifan Q Eco) has a 3/4" shaft,
but I guess that is about compatibility with other hardware
rather than an indication that the engine is itself imperial?
So, that was a bit irritating, but I have just looked up
Adrian's guide and it looks like I should be using M8s instead
of the 5/16ths. But then, isn't 8mm the equivalent of a 5/16th?
I am inclined to say almost that you shouldn't try to explain,
because this is the sort of thing I never fully understand! But
presumably the threads are different?
To avoid me having to take my engine to Suffolk Fasteners, can
anyone confirm that I need M8s? Don't clones for sale in the USA
have the same size holes - and if so, why would Comet supply
TAVs with 5/8-25x1" bolts?

I can't speak for your engine set up, but I had to order the
shaft bolt in UNF. the others were metric. Take care with the
shaft bolt and find out what it is. Mine started two threads on
a metric before going stiff. I used these, had to buy 5 so I
have 4 spare.

In (very) brief. There is no "standard" for the engine bolts.
Some have imperial bolts in the case, some metric standard,
some metric fine.

Thanks guys. In the end I just took my Lifan along to Suffolk
Fasteners in Ipswich and experimented with the help of the young
woman who runs the place. She was very good. She is the daughter
of the bloke who owns the company, Damian, who I met through
fencing (epée, not wooden rail) and who has supplied my many
projects over the years. Emma found that standard M8s fit, and
because it is the better type of supplier, she supplied just the
4 I needed.

I am a bit confused here myself. Are we talking about the bolt
that holds the clutch onto the end of the shaft? I have one
that is imperial and one that is metric.

Ah, your question explains David's response. My fault
completely, sorry. No, I was talking about the 4 bolts which
hold the torque converter on the engine.
All the explanatory videos on YouTube just tell you to use the
bolts that you already have with your engine, but I am not sure
that clones ever come with the bolts; mine certainly didn't.
(sorry for the confusion my question created)
