Read the articles here about the GM HEI module, if you find that your wiring is smoked or the factory Transistorized Ignition Unit (TIU), aka ignition module, is gone. You can run wires in the engine bay directly from that terminal block with the green and red wires. https://www.classiczcars.com/articles/electrical/

Is BSPT a possibility? The prevailing internet Z forums' "wisdom" is that the oil pressure sending unit holes are BSPT. JIS VS BSP: What's the different ?Before choosing a suitable thread standard, it is necessary to understand from various aspects. This article will introduce the difference between JIS and BSP, so that you can better choose the thread

Sounds like you're saying things have been just fine then something changed. As opposed to the brakes having always bothered you. If it was mine I'd find the source of the sudden problem before "upgrading" anything. Otherwise you could add the upgrades and end up with the same problem, never solved.

They run up to the ignition module. The module uses the signal from those wires to know when to create spark. Looks like this. Has many wires connected to it, including those green and red ones.

Here's a decent relay instructional video.

You can add a relay as cgsheen suggests, which will take the current to the solenoid out of the switch, or you can bypass all of the inhibitors and other safety features. I would start by checking for voltage on the wire that comes from S on the ignition switch when you turn the key to Start. If there's none there then you need an ignition switch. If you have voltage then you can add a relay or by pass each safety on the path to the starter solenoid. It would be best to also test under load, using a test light that draws some current, like a taillight bulb. I have found that the staked pins (copper color) can get loose and lose contact with the terminal. I had a 78 switch that would grab the starter then let go as I turned the key. The pin was loose. I fixed it with a hammer and a chisel. The terminals are marked with molded in letters. Look closely if you remove yours.

Excellent job reinvigorating a seven year old post!!! You're exactly right, things always come around again!!! Do you have bondo in your roof? How is Jan? Say hello to Dwight!!!

Good point!! 😄😁😆 What kind of car do you drive? Does it have bondo in the roof? ☹️

Nice catch. I read that comment but it was so bland that it was almost invisible. Thought it was a person commenting just to comment.

Apparently the seller wants ~$78,000. Had not heard of "Super Samuri" before. I assume the non-traditional spelling is intentional. Seems odd. Seems similar to the Scarab program in the States. Tip - if you highight the words in the sky they will change to text that is readable. https://www.samuri.uk/ https://www.samurimotorcompany.com/history-of-samuri-motor-company

Those knee replacements seem to be hit or miss. I've seen people with the good ones but also seen those with not-so-good. Hard to tell how to make sure you get a good one. If you're planning to get one do the research and try to increase your odds. Actually, that applies to any surgery in today's modern medical-industrial complex. Once you get on the conveyor belt it's hard to get off in good shape. Healing can take a while though. Those short-time "back to normal" piece-of-cake no-problems stories are rare.
