Started removing the transmission on the white '76 today and got stymied by a stripped cone screw. The front one was fine...but the screw at the rear of the car looked bad before I even started.

My search has yielded several options:
1. Use an easy out
2. Find the next size up allen head or torx bit and hammer it in. I tried that...didn't work
3. Use JB Weld and "weld in" an allen head or torx bit
4. MIG weld something on the screw (not an option..I don't have a welder)

Based on the latest and greatest minds, what's the best option these days?

Knock the bushing out of the way first. Plastic and heat dont go well together

Until you have stripped this screw, you aren't really a 914 mech. The extractor works just fine, but be careful with the torch on oily/greasy parts. Good idea to have a fire extinguisher handy. Generally a good idea around the shop anyway.

+1 for heat and an extractor to remove stripped cone screws. This process worked flawlessly when new shift rod bushings were installed in Yellow last year. The PO used Loctite to install the cone screws, and the rest is history.

I don't agree. Many times Loctite has been used. Heat will break it down and is necessary. Heat is your friend here

Definitely heat it! If you have a high power soldering iron that may be enough to help.

1. Clean off all dirt and grease
2. Spray liberally with PB blaster or Kroil, let soak for as long as possible, re-apply, tap with hammer to help oil penetrate
3. Apply heat

HEAT! Figure it this way: If it needed heat and you did not heat it, then you strip the extractor and it sucks worse. If you heat it and it didnt need it, no biggie.

And you are going to want to replace the plastic bushing anyway, so no biggie if it melts. Cheap and very easy to replace.

I figured "while I was in there" I would replace all the bushings anyway. Best source? I see pelican has a package for all the bushings from the shifter back.
