Robin's comments below:
"Dear all, After more than 12 years in the making, I'm incredibly proud to finally share "Finding the Heart of the Cobra", a story that goes far beyond a car.
This film is a journey into the soul of my 1962 AC Bristol, Chassis BEX 1213, the machine that helped shape what the Cobra would become. Along the way, I've had the honor of connecting with some of the very people who lived and defined that history, including Allen Grant, Peter Brock, Billy Krause, John Morton, Mike McClusky, Lynn Park, along with many others. Narration on this film is by Ned Scudder, bringing it all together.
What started as a passion project turned into something much deeper, a search for the origins, the spirit, and the people behind an icon.
This isn't just about horsepower or heritage, it's about heart.
Thank you to everyone who helped bring this story to life. The journey has been unforgettable, and now it's finally time to share it.

Last post by westcott - July 27, 2026, 10:48:18The cast Y headers were stored in one of the 100 boxes, not original but new repros stored for more than one decade.
Now I'm still looking for a slightly cudved nudge bar front with bumpers.

Last post by wirewheels57 - July 22, 2026, 10:25:54I am investigating bringing a batch of these tyres over from the states , they are no longer available in the Uk , at least I have not been able to find a supply .
These were originally used in the 30's by the factory ( I have a picture of my 16/80 in 1935 shod with these sat in the factory ) .
If any one is interested in joining this quest please contact me

Last post by westcott - July 15, 2026, 20:15:40The owners handbook shows a highspeed of slightly above 220 Km/h and a final drive of 3.31.
That makes sence because it is very hard to bring the car above 220 Km/h if you don't change the diff to 2.88.

Last post by dkp_cobra - July 08, 2026, 07:48:24Hi L,
normally, there are ID tags claiming the ratio (directly or two numbers which are the number of teeth of the ring and pinion) and maybe a further ID tag P-L saying that it is a power lock.
If these are missing you have to turn the input shaft and observe the output shaft. Maybe turning the input shaft ten times and look how often the output shaft has turned. If the differential shouldn't be a power lock (which I can't imagine) pay attention that both output shaft turn into the same direction with the same number of turns. Dividing both numbers gives you the ratio.
Kind regards,
Peter

Mk IV, Superblower, CRS and other Continuation Cars Forum / NEED HELP regarding Salisbury ...
Last post by cobra06FR - July 07, 2026, 16:55:51Dear All,
I won AK1317.
I know the rear axel is the original Salisbury part. However I have no clue what the drive ratio is for this axel
I hear it could be 2.88 or 3.15 ? Does anyone know with reasonnable certainty what was mounted in 1989 ?
My engine is a 302 SVO and the gear box is the Borg Warner T5WC.
If not, does anyone know how to figure out ?
The reason for which I investigate this is because I had a major failure of my gearbox.I think I need to chain it as both the entry 1 the main shaft have been dammaged. As the gear box has 50000 miles I think it is probably best replacing it rather that replacing these 2 shafts.
Obviously there has been a lot of different T5WC mounted on AC and mine does not have the gear ratios corresponding to the only one new T5 produced by Tremec these days. And the new T5 from Tremec has got a 5th gear ratio of 0.63 whilst my BW T5 had a 5th gear ratio of 0.68. My 5th gear was already a "good overdrive" and thus I need to know my salisbury ratio as the new T5 is even longer.
I do not want to run into a non usable 5th gear.
hope this is clear. Let me know if not, I would try to rephrase.
Many many thanks in advance
Looking forward reading from you.
With my very best regards
Laurent

My own one on the right has a welded assembly from original Ford lever with MG Midget handle/actuation.
