P,d,m brass fittings is it for imperial or metric pipe?

Two flecks and two convertor rings with luck you won't need to cut any pipe as they could be a straight swoop if you want to keep it solid pipework take 4 3/4 tap extenders

The pipe work is really tight space. I was going to use pushfit flexi with jg imperial conversion couplin.

I have never had to use push fit or flexies.
If the pipes are too short you can cut the front one out and do the back pipe first.
Actually easier anyhow to do that, even if pipes are correct length.
A couple of brass connectors and job done
