New Headliner Question

[jaak]

My folks got me a new headliner for the charger for christmas, well I just opened it up to take a look at it.......
Do the sailpanels get covered seperately?  I could have swore when I removed it, it was all 1 piece, but this has got one large piece for the roof (with all the pockets for the bows,  and 2 triangled shape pieces, I assume is for the sail area. then a yard or so extra material (I guess if you need it for something) I have seen sail panel boards on ebay and in paddock books, ect. do I need to buy these and use the triangle pieces to cover it with?? Any tips, thoughts, etc. will be appriciated.

Thanks,
Jason
