Default 59 Windshield Post Stud Metalurgy Question

I got the three 5/16 inch studs out of my windshield posts that were too short(only one of the four studs was long enough). Now I need to replace those three short studs with ones of adequate length.

I have 5/16 inch galvanized carriage bolts that I can cut down to the right length, clean the threads up and install the new front studs with loctite so they won't screw into the glass.

Question is this: Are the galvanized bolts compatable with the windshield post metal or should I try to get stainless steel or some other metal stud? I am guessing that loctite will also work ok on galvanized studs. I do have SS nuts to go on the galvanized studs.

Thanks, Doug

The primary metal in the door post (which are pot metal) would be zinc (along with various other metals), which is also what is used for the galvanizing on your bolts. Would be no issue using them.

The use of Loctite will prevent any moisture from creeping up the threads in any situation (acts as a thread sealer), and is a good idea to lock the studs in place.

There is possible concern with the use of SS nuts on galvanized (zinc) steel only in areas that see lots of moisture. But it should not be a concern in this application.

That makes sense, plasticman.....I wondered if the posts were made of potmetal. That's definitely what it looks like inside the threaded holes. I never realized that pot metal weighed that much....those posts are fairly heavy. So if I use the galvanized studs maybe I'll just go ahead and get galvanized nuts and washers to match.

Thanks, Doug

Which is why the tabs on original posts are so prone to breakage...

Absolutely, also as the convertible top vinyl ages it shrinks, placing more and more stress on the posts each time you latch the top.

Look at the postings on the forum for tab repair and you will see a 5/16" set screw that is screwed in with an allen wrench. It is strong ,easy to assemble and looks professional in the installiation.
Just my opinion
