Fitting instructions for TC2 top

[XAXA102]

Hi,
I own a 320 TC2 of 88, not pristine but in good condition.
The ragtop is worn.
I have in mind to fit the new top my self, but don't have any idea on how I can do it.
Can one of you help me?

Cabrio-verdeck.de seems to deliver quality tops. What do you think?

Thanks for your replies.
