F355 spider roof wont open correctly...help!

hi all.

my latest 355 spider has just had a new canvas roof fitted prior to my purchase.
the roof mechanism now has a couple of issues...

firstly, the roof frame when closing seems to want to come down on top of the seats even though the seats have went through the full moving forward cycle; they are definately as far forward as they should be....the only way for the cycle to continue is to use the manual lever 'tilt' the back of both seats forward...

secondly, the roof only then retracts down to the point where the mechanism meets the 'striking plates' that are located about 10" up from the floor base either side behind the seats...the roof then stops...it seems as though the passenger side is not 'sliding down' the strike plate...


the roof shall go through the close procedure, but is ever so out of align with the locating the locating 'keeper' above the passenger side sun visor.

any advice on both issues? are they related?

thanks for any help in advance.
