Posted August 11, 201212 yr comment_398300 I have 280Z hood with broken studs on the hood vents. Can anyone tell me a good way to repair/restud these vents? Link to comment https://www.classiczcars.com/forums/topic/44074-how-to-fix-hood-vent-studs/ Share on other sites More sharing options...
August 12, 201212 yr comment_398389 I mistakenly put studs on my headlight buckets by drilling out the broken bolts, (which I thought were studs) tapping the holes for M6 threads, then screwing in stainless steel bolts from the backside and applying JBWeld to the threads up against the head. They hold really well, so well in fact that it wasn't worth the effort to take them out when I discovered that the headlight buckets aren't supposed to have studs.

August 13, 201212 yr Author comment_398497 I don't want bolt heads showing on top of my vents, but I may fill underneath the vents with JB weld then drill, tap and insert new studs - being careful not to drill through the top side.

Rather than using threaded studs that could twist out again, I used screws of the proper thread size. I ground down the roundness of the heads just leaving a "crossbar" at the top of the screw. The result looked like a "T". I then put the screw, head first, into the drilled out hole where the original stud had been and packed it with epoxy. The "T" anchored the threaded part and kept it from turning or pulling out when the nut was tightened down.Dennis Link to comment https://www.classiczcars.com/forums/topic/44074-how-to-fix-hood-vent-studs/#findComment-398502 Share on other sites More sharing options...
August 14, 201212 yr comment_398548 I repaired mine using regular hex bolts. I ground the head to the right angle and shape to fit the vent, and attached it with JB weld. I also made a pattern from card to hold the bolts vertical until the JB weld cured.
