Rewriting

Would it be correct if I rewrite this sentence ' I haven't met James for 3 years' as:

'I last met James 3 years ago'
'The last time I met James was 3 year ago'
'It's 3 years since I last met James'

All are a problem. You meet someone once, and after that, you have met them.
If you want to do this as "see" then:

I haven't seen James in three years.
I last saw James three years ago.
It's been three years since I last saw James.

Is there a difference if I say 'it's 3 years since...' instead of 'it's been 3 years since..'?

In my opinion, "It's three years" is not grammatical. You need "It's been."

You could say "I haven't met up with James for three years" or "It's been three years since I [last] met up with James".

"To meet up" is not the same as "to meet" in this context.

In my opinion, "It's three years" is not grammatical. You need "It's been."

I get the point about the grammar, but it sounds OK to me and I must confess that I use it.
