Original L63-67 Corvette Spare Tire BOLT, GM 3841464, 2 different vendors?

[David L.]

Attached are photos of 2 original GM # 3841464 spare tire assembly bolts that are slightly different. In photo #1 the top one measures 6 7/8" in total length and has only the 3 radial lines (grade 5) inside a circle (see my drawing in photo #3). Photo #2 is poor quality. The bottom bolt measures 7" long and has the 3 radial lines as well as the 5 following letters along with a dash which appear to be "A R H O P -" but after searching the web it must be "A R M O R -" or ARMOR, the vendor.

Anyway, it appears to me that there were 2 different vendors that made these bolts but the more common bolts seem to be the ARMOR bolts.
I would appreciate any comments.

Here's a pic of three bolts that I have. The one rusted with the part number seems to be pn 3833819 and measures 7 7/8".

Can anyone place these on a mid year? The GM bolt is listed in the 1977 parts manual under 7.632 as 63-74 usage>

From Noand's book page 109 (prints) there were three different bolts, 3794107, 3833385, & 3841464
Looking at the heads it appears the head on the left was the 3841464 while the one on the right was the 3794107
However the 3794107 print seems to show both designs??? More things to consider

I have 3 original L63-67 spare tire carrier bolts, GM # 3841464 (6 7/8" , 7", and 7" total lengths).
I have 1 original 65-67 Corvette (5" + 2.5" thread length + 0.5" = 8" total length) "w/gold wall trim tire" spare tire carrier bolt, GM # 3872959 (see N. Adam's 63-67 book, page 300, and 65-67 Chevrolet Parts Catalogs).
I also have 1 reproduction 65-67 Corvette 7 3/4" bolt (Zip Product # TR 52A bolt, reproduction of GM 3872959 bolt along with a Paragon reproduction "U" bracket) that I bought years ago.

Note that the special 3841465 nuts are not positioned correctly as the flat portion of the special nut should be UP as stated and shown in the assembly manuals. I will have to remove the pins and reverse the nuts. I had removed the pin on the 8" bolt already to clean all the parts with my wire wheel but erroneously replaced the nut wrong.
Also note that the "dimple" on the original two 3841465 nuts are much larger than the "dimple" on the Paragon reproduction nut.
