This required its own page, because the passenger side manifold required some fettling.
When test fitting the manifold I found it to be pushed hard up against passenger footwell. I suspect this is because the whole body site 15mm towards driver side, as per design!
AK informed me to cut out section of footwell, and reverse it, so thats what I did. Multi-tool managed all of this in situ, but next time I will do it when the body is off.
