58-60 Grille teeth stubs

[Pat H.]

Does anyone know the correct length of the studs for the grille. When I had my car judged, the exterior judge said they were too long. When I disassembled the grille for re-chroming, there was a mis-match of studs and threaded rod cut off to retain the teeth. I bought new stubs from Paragon which are 1/4 x 20 x 3 3/4 in length. I have all the original retaining plates with "AAC" stamped in them. I was also told by another mater judge that the nuts used to retain the teeth had a captured washer/nut versus the nut and lock washer as described in the assembly manual. If anyone has a non restored car could check this out it would be appreciated. Thanks

i disagree with the judges opinion that the original nuts had captive washers. i've removed about 6 grills from 54-57's and none had captive washers, just a common nut and divorced lock washer. mike

Pages 87-8 of Noland's book would appear to confirm the now-faint memories of the Silver Fox......

I have two '59's here and looking at the AIM I think the judge may be right. I would have to dig deeper

Chevrolet Special Information Catalog (10-1-61) lists 58-60 grille bars (teeth) as being attached with:
1/4 - 20 zinc nuts part # 124818 and 1/4 - 20 zinc lock washers part # 120380.
Both of these items were also used on 53-57 grille bars (teeth).

I've got the nut and lock washer info, but I'm still looking for the stud length. In Noland's book, the stud does not have a part #. Could this be part of an assembly and if so, there must be some specs to what the correct length should be.

Re: 58-60 Grille teeth stubs

the studs that hold the teeth on the horizontal grill bar or the studs that secure the grill to the body? mike\

the studs that hold the grille to the horizontal bar

Re: 58-60 Grille teeth stubs

i went to the barn and have two complete 53-57 grills. i removed a couple of the studs that thread into the grill teeth. these studs are 3 3/4" long. the threaded end that screws into the teeth is threaded 7/8" of that end of the stud. the end that secures the grill teeth to the horizontal bar is threaded 7/8". There exist 2" of unthreaded stud centrally. its been my experience that the 56-7 exterior judges may be incorrect in their judging of these studs. the couple of 57's i've duntov'd since 2010 have had a deduction for incorrect stud length protruding past the lock washer and hex nut. there is no doubt in my mind that the stud i measured for you are originals. mike

Re: 58-60 Grille teeth stubs

Thanks Mike. I did take apart a 60 grille for a friend of mine and it had the original grille teeth that needed to be re-chromed. Those studs are 3 and 3/4" as well. I think I'll aske the team leader to confirm that yours and mine are correct.
