I don't think there is a repop.

Will an A body switch work , I have one?

Do you have one that needs repaired?
Jim at JS Restoration just did my switch. A lot cheaper than that price too. If there was a repop Brewers would be the first place to look.

Why do you need it?
Starting the cat with the clutch pedal in is not good for the thrust bearing.

FI doesn't matter, it's still hard on the thrust bearing. There's a reason Chrysler did not use them in the 60s and then again in the 80s...I'd fab up a neutral switch on the shifter before I'd ever run a clutch switch...BUT I've never felt the need for one, especially after losing a thrust bearing in a 273 many years ago...

Just run a wire from starter relay to ground, or get a pre '70 manual trans starter relay for the cleanest look. My '08 JK Wrangler has a clutch switch and I'm glad for it. And I never had an issue with the T. O. Bearing on my Bee with the clutch switch so will be reinstalling it just because it's supposed to be there. If you're not using the reverse lockout, just pull it into neutral before putting in the key.

Brewers core charge is less than the only original switch on eBay. What's your bumper worth? More than $250? Buy the whole rig from Brewers and have some peace of mind.

Starter relay to ground works for me for both clutch and NSS. Agree why do you need it?

It's not the throwout bearing that it's an issue with, it's the thrust bearing in the engine.

I replaced the crank bearings many years ago. The original thrust bearing was fine. This car saw 22 years of daily driving before replacement of bearings, multiple starts per day, with a clutch safety switch.
What problems have you experienced?

Change in Harleys to fuel injection around 2000.. Started using my clutch everytime before starting ( I know different mechanicals) when I witnessed a fuel injected bike start in gear and watched it climb a chain link fence at the Harley dealer.. Just didn't want to die with fuel injection..

It was a bad day for someone.....

After reading all the posts and reading your responses it only makes sense for you to pony up the money and buy the switch.

When I do a motor for a car with a clutch I modify the thrust bearing bearing so it pushes a pressurized oil stream back on that surface just for the concerns some have stated above.
