Thanks Stan. That said it all.

In '10' when I got inspected, the inspector wanted to make sure about my throttle return springs. He said "you have to have 2 return springs"  and I said, "does that mean I have to disconnect 5 of them?"
1 on each throttle shaft = 4, 1 on the linkage to each carb and 1 on the linkage to the bell crank.
He just smiled.

Thanks Ron.

Mike,
Emails don't seem to be working so I'll try this.

Terry, that will be perfect. Thanks so much for doing this.

God Bless you.🙏✝✝

Why building a long car in South Africa is such fun!!!!!.

Try buying a throttle body positioning sensor. The advice although vague was "Just get one off of a Toyota Corolla".
This is how it's been going.

What model?.
What year?.
Give me the VIN?.
Do you have a sample?.
Please bring the vehicle in for repair.
Sorry we don't carry the TPS, you need a new throttle body.

Don't say "Custom" application. Over here custom means a tradition. One off unique is not in the vocab.

Mike, any of your buds have a dead car that is equipped with fuel injection?  All of those have a TPS...

Mike, aren't all your bits 'bespoke'? 

[Crackerman]

If it were me, I would use a very common tps sensor if possible, and modify it as little as possible, so when it fails on race day, I can easily source another.

No friends with dead cars. I'd jump the wall but the neighbour's got a big dog.

Seriously, I've left it in the hands of my buddy Richard. We only recently hooked up after
15 years. He owns a parts store.👍👍👍

Thanks for all the sage advice. I appreciate every word.

I thought "bespoke" referred to wire wheels.

Weird stuff happens on this build every day.
I was Blessed with certain talents and I use them to the best of my ability.

There are areas where I'm out of my depth which is normal.

Here's my problem. I have a GM rear end and the ratio is 2.44:1 but I think it's a 7.5" as opposed to an 8".
Please correct me if I don't know what the heck I'm talking about. My Ford 9" set up was stolen by a thief along with
a large amount of cash who said he was a gear cutter. This rear end thing is the bug bear on the build.
I'm stubborn and I want what I want, period. I want a 2:1 ratio.

I found a company overseas that is prepared to sponsor my project with two gear sets and ship them to my door.
I'm grateful like you won't believe but they need DXF drawings along with material grade and heat treat specs.

My friend Ian could crank out the drawings in no time but he says I need to master AutoCad. He refuses to help.
Let's be realistic. A newbie with no experience has no chance of pulling this off. Any help or advice would be welcome.

I want to start 2019 on a positive note but this deal is giving me sleepless nights. Thanks for listening to my whining.

[Interested Observer]

If the "overseas company" is an experienced and reputable gear cutter, you should be able to negotiate the material and heat treat (and gear design, subsequent surface finish and treatment etc., etc.) with them based on their experience and your expected performance needs.  They should be interested in doing so in order to preserve their reptutation as a provider of quality goods.
If they are just a machine shop that thinks having a chunk of material and a drawing is enough to produce a viable pair of gears, you  would be well advised to steer clear.  A lot more goes into a successful gear set than just what it appears to be in the finished product.

There are many other and simpler CAD programs than AutoCAD that will produce a DXF file.  However, with any of them there would be a learning curve, and a gear design would not be one of the easiest ways to begin attacking it.

Much easier, quicker, and less expensive to replace the 9" or some other already established, and replaceable, set up.
