Crash bows: Engine protector holder breaks

On my '93 RD07 @ I use crash bows (Tanksturzbuegel) from the german brand
"Hepco & Becker".
These parts fit fairly well but still provide some additonal mechanical
tension
to the three basepoints they are mounted on each side .
(Each crashbow is screwed to the rear engine holder, the cooler base and
the front 
holder flap [Befestigungslasche] for the aluminium engine protector)
As a result of the tension the left front holder flap for the aluminium
engine protector broke off 
the mainframe.
I have constructed a much stronger metal part out of a piece of T-steel,
which supports both engine protectors 
and crashbow again. This part is screwed to the main engine holder located
between the two liquid coolers.
This solution seemed to be very stable. However, after a while I have
realized that now the 
relatively weak M6 screw where the crashbow is screwed to a fixing of the
cooler, was broken.
Obviously the reconnection of the tank-crash-bow to the third basepoint
brought the tension 
and/or vibration up again and destroyed the second weakest basepoint.
I saw several other @s with the same problem (broken front engine protector
fixing)

Does anybody have any good proved solutions, how to overcome the described
problem?

Gruss

Thomas
