Formula400, Compare the spring bolts to the fan shroud bolts. Are they identical but two different lengths? That would explain two different part numbers, but then it doesn't jibe with the washered bolt. Hmmm... We need more owners to confirm what they have.

That's why we have this forum -- to compare notes and try and figure this stuff out. That particular clip nut is better suited to the coarse bolt as well.
The 3968521 bolt is the longer version of the '0314 bolt and is used on the inner fender extensions. Last edited by FunctionalShaker; 06-22-2012 at 07:35 AM. |

So, you question on the rear light harness clips, the 71 and 72 i have here do have the round holes. The bolts for the shroud are different then the hood spring ones, the hood spring bolt is a tad longer anf the washer end is alittle smaller. Also, the 3968521 "longer" bolt is what was on the lower front fender to core support. The 0314 was to the rear...I'm really thinking the later 70 cars were somewhat being built per 71 specs from the evidence before me. If you look at a 71 assembly manual you will see what i am refering too. Look at my post #35, you will see the longer bolt Last edited by formula400; 06-22-2012 at 10:50 AM. |

Okay, that means that 70 appears to have a one year only trunk clip.
Re the fan shroud and hood spring bolts: That was my finding on my CA core support as well. Based on the part numbers etc., I'm beginning to wonder if the washered bolts are an aberration. (logic dictates use of the longer, coarse bolt) In the 70 ass. man., the '521 bolt also shows use at the rear hole of the core support/fender and the '314 filling the front hole. '521s were also used to attach the inner fender to the frame brackets at the firewall. Of course, line workers frequently mixed things up. They weren't thinking about us... Do the gusset bracket bolts have a different part number in the 71 manual? |

The gusset bracket bolts are the same part number
I'm gonna upload more pics for the weekend view and debate...lol |

I have written down the bolts were up for debate. but we confirmed these are correct

I have more pics, but lets see were these go for a day or two...

The last hood spring bolts with fixed washer are correct, to my knowledge. I have taken apart many 1970 and others and found the original ones to be just like yours, aside from the fact that the cars I dealt with were Norwood cars... which can make a difference sometimes

Based on our findings, I'm going to conclude that the longer, coarse bolts are correct -- considering the nut used and the length. Part # is: 9427275
Is it possible the washered bolts in question are part # 3846201, used to attach the center brace to the bottom of the core support? These appear to be unique to this location. The reason I question this is because I have found a short stubby bolt there as well. Pics to follow. Last edited by FunctionalShaker; 06-22-2012 at 10:16 PM. |

I know you're documenting the attaching hardware for now. But, did you find any date coding on the horn assemblies?

When I worked at the Framingham BOP plant in 1972, line engineers used TMDs all the time to substitute parts. A TMD is a Temporary Manufacturing Deviation.
The things that were chnaged most were fasteners. So, a car built one week could have variations from cars built before it or after it. Also, all of the painting was done manually, so there were variations there as well. The amount of robots doing work then = zero. All humans, with the dveiations from human technique. |

[QUOTE=formula400;4661346]Yes you have .
Off the top of my head i noticed the front intake bolts are not the studded ones, i'm assuming changed for some reason ?? QUOTE] Haven't taken the time to read all the postings yet, but.......those two right front intake bolts should not be the studded top type. No A/C option for RAIV TA, so the normal washer headed boltsa were used. |

Okay, I think we've got the hinge spring bolt identification squared away. I've posted a revised pic.
Next riddle to solve is that of the center brace/spar lower three '6201 bolts. From my research, these are unique to this location. I've posted a pic of the two most likely possibles. I know that '0314s have been substituted, but I'm looking for those that match the number. I'm leaning toward the one on the left. If anyone recognizes where either one of them goes, let's nail it down. I realize many of you guys don't care about hardware originality, but for those who do... Besides, it's fun solving mysteries. |
