Wheel stud install, '69 12 bolt?

Can I install 1/2 studs in 1969 12 Bolt axles instead of the 7/16 I removed the studs that were in it before I shipped here as they were long, and if so which studs?

If the axles are drilled for 1/2 inch studs then you can install them. If they are not drilled for 1/2 inch studs then you will have to get them drilled.

The axle has 10 holes for studs 5 smaller and 5 larger ones they all seem to have the lines like stud can go in, did some axles come with option for 7/16 and 1/2 ? And yes I will be changing brake hardware 😀

that looks like a factory axle;
however i've not seen any other factory axles with dual stud holes
by any chance are there threads in the axle flange to accommodate screw in studs??
measure the holes if no threads are present,
this will be needed to get the correct stud knurl area,,,

on closer look at the photo,
i see the previous knurl lines from the studs installed in the larger holes;
find those same 1/2''studs and you are golden

Those are factory axles that have been drilled for larger studs. You can send axles to Moser Engineering and most machine shops to have them drilled.

Freddie,
Not sure about your area, but around here there is no shops that will touch an axle due to liability concerns. Just wanted to mention that because I get calls fairly often to do this and even if I had the proper equipment to do it my insurance would not allow it.



I have a couple of friends with precision type machine shops and they wont touch them either
