There was a short period in 12 cab Chevrolet production when Ford bonnets were fitted this can be seen in period photos. I can't remember ever seeing an explanation for this does anyone know the answer? my old C15A 12 cab had a Ford bonnet and several other restored 12 cabs show the same feature.
Looking forward to following following your trucks progress lots of photos please.

I noticed the 'bulge' yesterday - the radiator filler neck bares no relation to the bulge, now I know why! If it was the truck in the 1981 photo, it certainly had the Ford bonnet back then!

hi Richard

The Rochester would be a better carby . The 216 version has the smaller throttle bore. The 235 version seems to be more common over here , it has the larger throttle bore.

There is a weakness in the C8 drive train, the uni joint just behind the gearbox tends to fail. The uni joint is inside the round sphere , it drives the shaft inside the torque tube.

Do a search on this forum for C8 .

The front wings on your C8 look a little odd , sort of like somebody has made them in the back yard ! if you can find them, the wider wings from the larger 15cwt or 30cwt or 3 tonners will fit the C8 . You must narrow/cut the wider wings down , make them narrower, that's what the factory did ! The 13" wheels do appear to be "out of scale" under those huge long wings !

Hi Mike,

The Rochester carb is off a 216 of slightly later vintage. I'm going to refurb it and use it until I get the carter done. I need to be able to keep the C8 mobile while I do the work as I am limited on space and have to move it around.

I have heard about the universal joint - is there anything I can do to help its longevity?

The wings are wider than the rest of the truck! I thought they looked a little odd compared to the wheels too. I'm not familiar with CMP vehicles at all, so I wouldnt have known if they were right or wrong. The proportions dont look quite 'right'. They've certainly been on there a long while looking at the rust and the fixings on the brackets holding the wings. That will be something to look out for in the future. One good thing is that if the front end goes through a gap, the rest will too!

Thanks
Richard

Thanks David, with the posts Hanno provided earlier in this thread and the link you have given me, I've got quite a bit of history to my C8 already!
This forum is pretty amazing! Thanks everyone!

Richard,

Welcome to the forum and congrats on the purchase of your C8! Lovely truck!

Pattern 12s have a peculiar problem the placement of the airfilter can let water drip into the oil bath raising the level of the fluid in the filter so that engine has trouble breathing.

Once again....a vey valuble piece of info, Phil! I have to check if that's also the case with an 11cab....even though that has rain gutters along the edge of the engine cover.

Alex you make me wonder do any Pat 12s have the little gutter under the hood at the windscreen edge like the Pat 13s?

I agree good to see another CMP being enjoyed by new owner, keep us posted Richard.

Cheers Phil
