Madmtnmotors-
Good advice on the acorn nut. Both acorns were stripped. Have some nuts I picked up from the specialty bolt store downtown when I picked up the die that I can use until I get the replacements oem acorns coming from partzilla. I’ll follow your advice and use the nuts in the process of fixing the threads.

Oh, it is only $34! Says metric and 10mm is in the range so that looks right. I went ahead and bought it. Arrives Sunday.

So now the question is which tool to use first...

I’ll probably practice on some old rusty 10mmx1.25 bolts. Mash the threads with some channel locks or a hammer.
Excellent plan!

Thanks all!!! Would have ruined these shock mounts without all your help!

Update: decided to start with the thread chasing file. Practiced for 15 minutes on a old 10x1.25 bolt that I purposely mashed the threads on, then I took my time filing the shock mount (using a circular motion, credit BenelliSEI), finally was able to partially thread on a nut, so oiled everything and ran the hex die down the threads. When I thread on a nut, the threads feel like the other shock mount.

 Way to go, it looks good. .
 You have a remarkably good attitude  to making a proper effort to repair  it.
 Unlike some on here that are offended, when it gets suggested they buy a pitch gauge to measure their threads...

Thanks for the affirmation guys!

Gramna2-
I had purchased the hex die before posting, mentioned it in the initial post. Everyone (wisely) talked me out of starting with the die.

Well done. Patience usually wins in these matters. I used to get upset over broken/damaged bolts/threads, but now when damaged fasteners rear their ugly head my first thought is to start formulating a plan as to how best to approach the repair.  8)

 Got a funny story. .
 A guy from a neighbouring shop brought in a shaft with a damaged thread.. so I fixed it with a triangle  file and a thread file ... but in the lathe.... he got sort of quiet as he watched.. and then he said I got one of those..did not know what it was for !
 I said well I have charge you a bit..it was like 8 bux or so.... But I added now you know what  to do next time., I said how did you end up with one, big knowing what it was for... he said he got a few tools from his Grandpa..

Haha I can relate. Caught the end of an estate sale one time and they hadn’t sold much. I asked how much for all the tools and hardware. And they let me have everything for $100, filled up my trunk and every bit of the cabin of my car. The guy had a window dressing company before he retired, so there is a lot of random tools and window hardware. I wound up pitching half of it, but what I’ve kept has saved me many times my $100. I’ve figured out what a lot of stuff is over the years. But every once in a while come across something that stumps me. Both files I had pictures of in this thread were from that window dresser.

I may have mentioned this before, but my thread chasers and a set of Greenlee Knock Out Punches came to me the same way. I used to “borrow” them from the mechanic at a Texaco Service Station. It was at the end of the block, when I was a kid. Bill repaired the end of an axle on my mini bike. I pumped gas at the station, the summers I was 14 and 15 years old ($1.00/hour + tips). When Bill retired a few years later he said: “you use these more than me” and gave them to me. I used the punches for putting holes in alloy panels in my race car...... he was a cool guy and I still enjoy those tools. 50+ years later.....
