Happened across this quite by accident as a friend asked me to phosphate a few screws.
As it turned out they were for the support bars from the fender to the radiator support.
Told me his restored 69 had pointed screws and Brian Henderson told him they should not be pointed.
So he took the ones out from another non-restored 69 he had. I told him I was not aware of this but would check our 69.
Sure enough our 69 has the non-pointed screws as well so I check our 69 AIM vs. our 68 AIM.
69 AIM p146 UPC 11-13 B3 calls out two different screws for that support bar.
Support bar to fender screw #3960314, support bar to rad. support screw #3846202 (hard to read in our AIM).
68 AIM p142 UPC 11-13 B3 calls out screw #9780122 both ends.
Our 69 is a 10D (Oct. 69) but not sure of the build date of my friends donor 69.
The #3846202 in both cases are a non-pointed 5/16-18 X 9/16 lg with 3/4" captured washer.
Please note the two to the left are our 10D screws and my friends all had the same 'D' type mfg. screws.
I assume they made changes from 68 to 69 due to possible wiring in that area of the rad. support.
