Trying to verify original radiator mounting bolts

Sal
In the 69 Camaro AIM, radiator and fan shroud, UPC 11/13, B4, item #2 Is listed as 3960314 with R1 next to the pn. R1 dated 10/68, states it WAS # 9780422
Both of those bolts are shown on AMK PDF file pg. 117 row 3. (all 3 picture in row 3 )
It looks like the 0314 does have the threaded point, AMK lists this as a 1970 body bolt. And 0422 is listed as a 64-69 bolt.
So, just going on the AIM, that bolt you posted could have been used ??
What is the build date on you TT ?
Maybe Shauger or Chris White can add something, being Vintage certification guys ?
