Replacing Rear Shocks -- Spindle Pin Questions (of course)

[thumper300zx]

I have new rear shocks for my 71. Of course in my haste I start following Haynes instructions and quickly run into spindle pin removal issues. Started researching and found the long history of these pins. I have the set pins removed (which weren't bad). I started backing out one side with washers and the original nut. It's about 2" out but the threads are worn out now and I consider one side's pin destroyed. So, I pulled both sides by removing the inner side of the control arms. I have them off the car.

I'm not planning on doing any crazy suspension mods on my car. Just want to get the shocks in and get it back together. I could probably just throw one side back. That side I couldn't get the spindle pin to budge, so it's in there, but the threads are fine. The side I was working on will have to be replaced. I would be willing to replace the bushings -- if I do that, would I buy stock spindle pins and just put it all back together or do you go with the 5/8" pins?

Do you mean 5/8" bolts in place of the proper pins?  There was a whole thread about the 5/8" bolt on another forum.  At the end of it, people were grinding notches in the bolt for the lock pin, essentially making a factory pin.  It's good to know if the spindle pin supply dries up but there's no benefit to the 5/8" bolt over the pin.

Use a torch on the casting and the pin will be easier to remove.  The hole will expand.

Lots of never seize on the new  spindle pins and they will slide out easily the next time.  Next time will probably be about 20 years...
