convertible top main bow extension help!

[Pookie21879]

Hey guys
So I have talked to Letas top shop on this and I need to get the measurements for these so she can make them for me so that I don't need to pay more than I have to for this. So if any of you out there have the same boat and top as I do it would be a great help to get the measurements I need for the MAIN BOW EXTENSIONS so I can pass the dimensions on to Letas. My boat is a 2001 Maxum 1900sr open bow w/5.0 mercruiser.
thanks for the help.

Here is a pic of the same top that I have. Not my boat and sorry if this is one of yours but I just pulled the pic from Google is all
