It's been a long road, now you need to find a long long road. Enjoy.

Thank you! I missed the sunny, nearly 80° weather here a couple of weeks ago, but I'm hoping to get out tomorrow. It's predicted to be in the 60° range...

Following a recent engine oil and filter change, the bonnet was opened to check for any leaks. On reclosing the bonnet, the nearside rear catch knob literally came off in my hand! Don’t know if the bonnet knobs are OE or aftermarket items but the catches have never required gorilla strength to release, so this came as a surprise.

The threaded extension to the catch knob had sheared off at the outer face of the sliding plate and the inner portion of the thread with hex nut remained in the sliding plate. Access to release the catch from inside the bonnet looked to be challenging.

The adopted solution below.

[Linked Image]
The threaded portion remaining inside the sliding plate was drilled out from the outside and ultimately fell to the running board, complete with nut. The thread was confirmed as M6.

[Linked Image]
The knob was drilled to 12mm depth, starting at 2.5mm dia and working incrementally up to 5mm dia. The swarf revealed the material to be brass.

[Linked Image]
An M6 thread was then cut to full depth.

[Linked Image]
A 25mm length of stainless M6 threadbar was screwed into the newly cut hole, sealed with threadlocker and tightened.

[Linked Image]
This assembly was then screwed into the sliding plate to enable the bonnet catch to be released. A washer and stainless nyloc nut clamp the knob to the sliding plate, thus making a connection somewhat stronger than the previous arrangement. Job done.

Now that one has failed, more are likely to follow. A winter task will be to strengthen the remaining knobs in like manner.

Great job Chris thumbs. I was surprised the remaining stub couldn't have been removed by turning original locknut. Is the sliding catch plate threaded itself or just 6mm clearance thinking

Photo below taken whilst making my bonnet stays shows reasonable access to catch release locknut.

The sliding plate was threaded. Access to the locknut somewhat fraught when the bonnet is closed sherlock

Just for info, the older Mogs have a 1/4 BSF thread on the bonnet knobs, just to be really awkward!
