Here's a shot of the windshield armor bolts on an original (1950's BM rebuild) halftrack. The bolts barely engage the locking part of the lock nut.
I just bolted my hinges on with 1 1/4" bolts...the repro hinges are probably slightly thicker than originals, and the locking part of the nuts don't engage any threads on the bolts. I used some Permatex threadlocker, just in case. Would like to swap these out for some longer bolts if anyone finds a US source.
*sorry, can't fix the pic orientation...don't know why this site does this to pics
