Greenhouse, How many clips?

Wappers

I have got a 2nd hand greenhouse, but unfortunately I didn't take it down, I expect there will be many missing, judging by how many bolts were missing.
How many clips do you think I will need for an 8x6 greenhouse?

Detailed info:
Two types of clips W (holding glass in frame) and Z for overlapping panes.
How many of these do I need for each overlap and pane?
The greenhouse looks a bit like the following picture, all sides and roof panels are 4'x2' (i.e. 2 panes)
The greenhouse will be fairly sheltered and be glazed with horticultural glass.

I got 4 packs of 50 with my 8 x 6 greenhouse and used the lot so 200 is a good estimate !

If you allow four W clips per pane and two Z clips per overlapping pane you shouldn't be far wrong.
