Shock absober brackets

[bz100]

Hi,
I need to make two of the shock absorber brackets to be fitted under CP3 and CP4.
I cannot compute (with Solid Edge) the flat part on pg 148 in the book, to achieve the ref dimensions given for the folded part.
Is the brackets made by various people/companies 34mm wide (inside), and the 12,5mm holes are 27mm up from the bottom of the brkt? If so I rather make the brkt fit the 34 and 27 dim and forget about the flat pattern.

For the rest of the chassis wishbone and schock brkts I will most certainly buy made ones.
