I used to have an f4 van in the 80s and i designed a fabulous roofrack which a metal fabricator friend made for me.I could fit an 8 by 4 sheet of board flat across it and it went out over the roof.I will try and find a photo of it and scan/ send it to you- better still as its quicker send me a mailling address and i'll do a photo copy.
