Bonnet Strut

 The worst thing about this build as it nears completion, is that I am faced with all the jobs that I have been putting off because I didn't fancy doing them any earlier for one reason or another.

The next item on this list is the boot and bonnet struts. Having had a good look at a factory car that was on the GD stand at Silverstone Classic, I felt somewhat more confident and decided to take on the bonnet strut first. Andy said he could supply a bracket for the boot strut, so I will leave that again for now.

So on to the bonnet strut. I had originally planned to fit gas struts but because I have fitted a stainless header tank for my washer bottle, I don't have the room to do this now.

The standard strut has a bracket at both ends. One of these needs removing as it bolts straight through to the inner wing.

The bracket is removed as the lower mounting is simply bolted onto the inner wing
Positioning of the strut is critical as you need to ensure that you get the maximum amount of opening but without the strut actually fouling. The lower mounting position is fixed first. This is broadly in line with the chassis cross member that supports the header tanks. I drilled a hole and then fitted a Rivnut and bolted the lower mounting loosely in place.

A bolt runs through the strut as is locked in place against the rivnut using a plain nut. A washer is then fitted between the locknut and the strut and a further washer sits between the bolt head and the strut
I put the strut in its closed position and then opened it back up about 10mm to allow some free play. I then put some masking tape on the bonnet and wing and marked the centreline of the upper mounting bracket onto the tape.

Before doing any drilling, and remembering that mantra about "Measure twice, drill once", I used some duct tape to test fit the bracket in place and check the operation. Once satisified this was all ok I drilled the holes to take the rivnuts.
