Hi Rich, close up photos attached and some basic dimensions, the bracket that the throttle cable attaches to is offset with a slight angle on it which is difficult to put exact dimensions on but hopefully the photos will help you to make something suitable

Alex, that is really excellent detail! I was hoping for a couple of pics and that would have been a start....but a full CAD drawing!!!! You are a star! I have the throttle cable on order which should be here this week, so that's my weekend sorted. Thank you!

Default Throttle bracketry

Thanks to Alex's accurate measurements and brilliant CAD drawing, I finally got the missing brackets fabricated - amazing what you can do with a vice, a hammer and an angle grinder!

Just missing the bolt to hold it to the manifold so thought I would check with the wise before I knacker the thread - a 1/4 UNF only goes in one turn so I'm thinking UNC for castings?

Hoping someone will know....

Great work Rich, really pleased it worked out, you could go into mass production now and probably make a few quid

Hi Richard, I can't find an exact reference for the accelerator bracket bolt specification, but it's likely to be the same as on the Spitfire. That uses two HU755 setscrews, which are 1/4x5/8 UNC. That would explain why your 1/4 UNF jams in the thread.

Rimmer Bros. have them in stock at 37p plus 13p for the locking washer -

Thanks Mr T - that's the mystery solved then! Ironic that the shipping is ten times the cost of the part!! With a bit of luck, I can go for a proper start this week - complete with cooling system plumbed in :-)

Most British cars of that era will feature imperial thread sizes, UNC and UNF being the most common. The Yanks still haven't gone metric so these old sizes still feature on their new cars to a large extent !
Saying that just about all European cars feature both imperial and metric sizing to this day, when was the last time you bought a fully metric tyre ? The width is metric but the diameter is imperial, lol !
