Back again. After getting a new centre vent from a chappie in Vic, I thought all my woes were over.
The new unit arrived - but alas was smaller, so somewhere between 90 and as it turns out 94, the designers and their french curves have redesigned the C4 dash and instruments.
But other issues reared their ugly heads, which resulted in seats out, centre console & shifter panel and centre instruments out.
Never seeing an original C4 90, I had not realised the original centre consol & shifter & centre storage compartment actually slope down to the left (original drivers side) of course the converters have cut & pasted and inserted packing blocks to level everything up to the right hand side. This has caused everything to be out of plumb, nothing goes together easily - so back to square one.
Starting with seat belt sockets, refitted correctly, then refitting and moving forward, now everything slots together nicely.
BUT! There is always a but, typical on jobs like these, even though everthing except the seats stayed in the car, I'm now shy of the circlip that secures the Shifter knob & button in place.
I dont even know what size it is - blo#$%^ hell.
