How do you install a Mikuni TMX 27 carb to a PX engine fitted into a VBB frame

Hi,

I was advised that you could install a Mikuni TMX27 with a Polini manifold onto a PX engine that is fitted into a 1962 VBB. I cannot see how this will work as the space is extremely limited and the carb is at an extreme angle sideways! 

 

Can it be fitted and if it can, can someone please advise how?
