Front upper ball joints made.



My front and rear hubs have arrived. Just a little bit of machining to do... wink



Front suspension taking shape.

I don't have the spec sheet to hand, but I seem to recall it is medium tensile C1040.

Ok, easily machined and more than suitable for your application, I doubt rust is a problem where you are so pitting will not be an issue, are you making them yourself or subbing out to a machine shop?

Unfortunately I have no machining or metalworking skills, so the lads at Classic Car Developments are doing all that. I built the engine, do tinkering where I can, and sourced many of the parts.

Steering column serial numbered and sent away to be crack tested for certification.



When one is 76 inches tall, fitting into a car only 40 inches high was never going to be easy. However, with some trimming here and there and locating it 75 mm further forward and a fraction more to the left than it was designed to be, the pedal box is trial fitted. The good news is that my legs end up at a comfortable angle. Now we just have to figure out how to route the speedo cable, hand-brake cable, and the plumbing for clutch and brake hoses in a cavity that is half the size it originally was...

With the hubs all finished we were able to trial fit the wheels and check caliper clearance. First time with all four wheels on. Doesn't look too shabby.

Just wait until you read the specs of the 1.0 ecoboost engine he's built to go in it! So much better than the diesel he was originally going for.

Are the tyres on par with modern tyres? Do they just look retro etc.

Thank you. I, unfortunately, play only a very minor role in any fabrication. I'm working with a team of very talented craftsmen who are able to perform what appears to me to be black magic. My role is limited to building the engine, choosing colours/configurations (mostly based on old photos), tracking down occasional bits of information, sourcing parts that we cannot or need not fabricate, and paying the bills. When finished the car will be the fulfilment of a dream I have harboured since I was 14 back in 1966 when such cars won Le Mans.

They are AVON CR6ZZS. DOT legal radials, so made with modern materials, but after the style of older tyres. They are used by a lot of the GT40s (and other cars) in present day classic car racing. Not a lot of choice out there in wide modern tyres that offer decent grip if using 15" rims.
