Remove stud from mirror bracket
 

What is the best way to remove a broken stud from the stainless mirror bracket???

Re: Remove stud from mirror bracket
 

Pictures would help, or more info. That is a pretty vague question.

I would start by soaking the whole end in penetrating oil for a few days, then put a little heat on the bolt itself. A propane or Mapp Gas torch might do it. Let it cool back down and put more penetrating oil on it before trying to unscrew it. If you don't have enough penetrating oil to cover the whole end you can make some using ATF and Acetone mixed 50/50. It works good. Just remember that all of that stuff is flammable....

If, after you do all that Leon mentioned (and it's important to do that first), and vice grips don't hack it - you might consider drilling a hole through its width so that you can insert a metal shaft and get some leverage on it. The shaft will have to be small dia (probably no more than half the diameter of the stud) and you'll have to ensure you're very centered when you drill. Only drill the hole very slightly larger than the shaft you find to stick in there - i.e. get the shaft before you drill the hole. Last resort is to just search for the angle arm replacement on the parts board. But folks usually like to sell mirrors as a complete assembly. A WTB ad for just that part might turn up a spare someone has lying around.

Huh, I thought those were integral to the mirror arm and not studs.

Good catch Leon, sorry didn't catch that.

BBCamaro - highly recommend the few bucks a year to subscribe, it's worth it.
In addition to that - you might bum an arm off the 8 lug slot dude if you give him a call:

I think you're right Pete, in which case it might take a little more leverage than gained by drilling a hole and sticking a bar thru it... ::lol:
Now this makes me want to go get up and check my mirrors - but I do seem to recall this being the case the when I had the DG4s apart on my white C20. Hmm.
BBCamaro - recommend yank that washer thingy off and confirm.

I’d love to be wrong as I have an otherwise nice arm in the same predicament. I also have a Nos pair of arms and I remember thinking the threaded ends looked as if they were spun from the metal. In later years the arms had threaded holes and affixed the mirror with a bolt.

-
I've never had one apart. I was just going by what the OP said about it being a bolt.

They are, in fact, part of the elbow/arm, not studs. The elbows were also chromed steel rather than stainless. I was faced with the same dilemma a number of times over the many years I've owned my truck.

My solution, but perhaps not desirable to a purist:
As DeadheadNM mentioned in post 10, later years were tapped for bolts. A couple of other advantages of these is that they are stainless (so they don't rust) and were used by other manufacturers on their vehicles. Disadvantages are that the lengths on each side of the bend may vary and bolts just don't look correct. To take advantage of the pluses and minimize the differences, I made stainless studs by cutting off the heads of stainless bolts and found some acorn nuts with the right shape. The only acorn nuts I found that had close to the correct shape were the chrome variety. The only other things needed were some stainless washers and some nylon washers. Pictures below show the details on the originals and what I did.

So I take it that you used the elbows off another, newer type of mirror? Looks fine to me. I would be very happy with that result.

Correct. I think those pictured came from a late 70s Chevy van. I have found similar arms on some Ford trucks as late as the mid 90s. Many have some dimensional differences. Some tuck the mirror head a bit closer to the door if mounted with the shorter "leg" in that position. Attached is a picture of a mirror on my truck with an arm having a slightly shorter leg.

Thanks for all the info .. they are indeed part of the arm and not a stud .

Re: Remove stud from mirror bracket
 

Has anyone ever tried to drill out and tap the arm?

Looked on the clearance pile this afternoon. Have two complete units. One with very bad chrome and one that came painted. Both looking for a new home. Will try to get pictures tomorrow! No mirror heads.
