Hi Guys
I am looking for further information on the following part.
It is the frame that supports the front of the forward canopy frame.
It looks like an aluminium casting with 3 large holes in the front face.
My question is what was the purpose of these holes?
It looks like they were conected by passage ways within the casting is this correct?
Any information, dimensions, better close up pictures would be welcome.
Regards
Drew
