Number 3 grill

Of the four variants of 2CV grills the third (number 3) is my favourite – this is the three bar aluminium version (1965-1974). As the bonnet opening was the same shape for grills number 2 to 4 was the same they are interchangeable and the plastic number 4 grill on Judith was broken I picked up reproduction number 3 grill to replace it.

After taking off the old grill, the mesh stone shield that sits behind it and the numberplate I was faced with the old enemy: iron oxide. Round the edges of the bonnet opening the paint had been chipped, the numberplate rubs on the central fold of the bonnet and had gone back through the wafer thin paint, and the mesh was starting to pick up some surface rust. There was also a slight dent in the bonnet at the offside top corner of the opening. Still, an initial dry fit of the new grill looked good.

After a somewhat inexpert bit of panel beating on the dent, a clean-up of the rust, some rust remedy, etch primer on the bare metal and a keying of the old paint, the bonnet opening was ready for a re-spray.

My rattle can technique needs some work as there were a few runs in the paint (holding the can too close and trying to put too much paint on in one go) and it was quite cold so it dried a bit matt. However, it’s going to be hidden behind the grill and numberplate so a good place to practice.

After the paint had been left for at least a week to cure (another learning moment) and the final touch ups had been done (and left to cure) the grill could be fitted. The plastic number 4 grill clips in but the number 3 needs bolting in at the top: for this I used countersunk, 16mm, M6, stainless, hex socket bolts with nylock nuts and a broad washer. It has two tabs on the bottom that need bending over to secure it against the lower lip of the opening. The mesh had been coated with the trusty satin black and is held in at the top with the new bolts and at the bottom with the original screws and washers. Finally the grill surround needed a bit of gentle bending to conform properly to the bonnet.

The last thing before re-fitting the numberplate was a strip of anti-rub “helecopter” tape down the centre line fold of the bonnet to protect the paint from rubbing off again.

All that’s missing now is a set of chevrons for the bonnet.

Replacing 2CV rear wing retaining screws

Although someone had painted the heads silver, the original rear wing retaining screws were rusty – to the point one had seized fast and had to be cut out when we took the wings off during the rechassis.

SPOG do replacement stainless screws for these so I picked up a pack.

As we’d done the hard work when we took the wings off, and had reassembled using copper grease, the old screws came out one at at time to be replaced with a new one.

As the rivnut at the bottom of the offside wing had been seized to the screw and had come out I used a flanged stainless nylock nut for that screw.  (Standard M5 0.8 thread.)
