The part has been delivered and fitted and on the whole it's a very good peice of kit. It was delivered in a modest Jiffy bag with a peice of polystyrene to protect the arms which although was adequate on this occasion might not be enough every time. Even this time the polystyrene showed signs of compression and breaking. But all good. It's a very nicely engineered little component.
Fitting wasn't as easy as I'd have hoped. I followed one of the many videos which show the lid being dismantled to fit new catches and all I can say is that it takes a whole lot of force to separate the Base from the top pad as they are bonded together in two places. Once apart though it is easy to gain access to the area involved.
The second problem encountered is due to the fact that because the new part is such a good fit it was impossible to get the pins to locate into the holes that they sit in. There just isn't enough give in either the arms or the fitting to allow it to be just wiggled in unfortunately. I ended up breaking one of the fittings whilst trying to prise it open which at first was a worry but actually turned out to be the best thing to have happened. As it's a bendy type of plastic and not the sort to shatter and break off I was able to open it up to get the new catch fitted and then close it again to its original position. A spot of superglue has sealed it up for good again.
All back together and in the car and it works perfectly. It looks good (for now) and complements the other touches of aluminium around the cabin. I can't see it, or the fittings that it locates into ever failing to be honest, the only thing that might eventually go is the spring but we will see. The only thing I would say is that because it is just bare metal, and a soft one, I've noticed that it already has a very small mark on it which I assume my missus has done. I'm not expecting it to stay perfect for long that's for sure.
All in all though it's a very good little fix and I don't see it having to be re-addressed any time soon. I actually expect that more likely I'll be replacing it for looking tatty long before it ever needs to be replaced for breaking, but then I am a fussy bugger!
Hope this helps anyone thinking of doing the same, I certainly don't regret it at this early stage.
Regards all.
