It may be that the tti mounts are that way for header clearance, I know it's really really close in there, had to trim one bolt head on the friverside so the headers would sit flush.

Did Don's tank have the vent bung on the passenger side? Mine did and it sits right against the rail, can't use it and will use the sendor or the 2nd sump line for the return.

I was shooting for next week for trial motor fitting but it got pushed back to repaint the engine compartment
