I'm not disagreeing on this point in particular, but I would NOT use that book for a restoration or as an authoritative source for E-body information. It has numerous well documented inaccuracies. Its does have some nice photos tho...
According to Paul Herd;Part #3417069 was an option on a GC after Nov 25th 1969, option J54. It had to include hood hold down pin option J45. The call outs on a 340 would read 340 Four Barrel.So it was not an option on early cars (mine was built in Oct).I think if you have a rare numbers matching car, addition of a part that was at least available is not a bad idea (to each his own). After all, it is known that some options missed getting on the fender tag.And it's a great hood.
Dec 9th 69 was only 3-4 months into the `70 model year so would be fairly early iin the producton run.
