May I am just slow but there is so much verbiage in this thread I have trouble just keeping up!
Marty : I agree; however, this has turned into a question (the OP) where we don't have a definitive answer. The MPC's and Assembly Manual all show 6 Clips; however, only Richard's (a 67 non GT Coupe) has met that criteria. Both John's and Jeroen's (early SJ Fastback GT's) have only 5 - and what appears to be different spacing. Then my early Dearborn non GT Convertible with 7 Clips. None of these, I feel, answer Ralf's original question for an early SJ GT Convertible. I think we need some input from early (or maybe late too) GT Convertible Owners.
I've attached a spreadsheet that I've worked up based on the information we have so far, hopefully to make things a little mor clear (and hopefully have something to add to it).
Than I take this sketch (only question what are the measures on the questionmarks? Alternatively could apply the sketch from Ruppstang below, even it is 1969.
Or should I use really only 5 "cheating" clips, because of my CV, GTA and San Jose built? Than I'll take Jeroen's....or Richards....or Johns.
Hmm...I'm still unsure and confused....
But hope the "Concours Specialists" will give me a clear advise/recommendation for my car.

Ralf : Yes, as Marty noted, this is getting confusing, as well as not getting an answer for your original question (maybe the spreadsheet will help a little).
In regard to my "doctored up " drawing with the question marks, those were because I didn't realize where Richard's 14" measurement was taken from. Now that he has clarified that, I have revised the drawing and sent it to him. I'm waiting for him to confirm my revised drawing and will then Post it. But remember - his dimensions are for a non GT Coupe.
As far as what you should do, if it were me,
1) I would NOT use the 1969 instruction because the spacing appears definitely different than any reported so far.
2) I also would NOT use any of the Fastback GT dimensions as we don't know if GT Convertibles were the same.
3) I would NOT use my Convertible dimensions (once I supply them), as it's from Dearborn and a non GT.
4) Finally, I would wait a while, if you can, to see if we can get some responses from SJ built GT Convertibles. To me, this is the best, and hopefully most accurate option.
