After reviewing the Dave Graham body assembly manual (also Jim's spreadsheets) for the following under the hood OEM bolts, I came to the conclusion that I have a number of incorrect bolts.
Listed in the assembly manual drawings:
382711-S2 Horns @ radiator support) 2 req.
57039-S2 Hood latch bar / hood 2 req.
57039-S2 Hood 57039-S2 latch bracket top / radiator support 2 req
57039-S2 Hood 57039-S2 latch bracket bottom / radiator support 1 req
57041-S2 bracket assembly / body @ shock tower 12 reg.
57041-S2 Hood hinge / body 6 req.
57041-S2 radiator support center bracket top 2 req.
The common theme is all the bolts listed in the assembly manualare phosphate and oil finish. The dimensions are the same with the exception of thread length variations of 3/4" or 1". The horn bolts also have serrations on the lock washer. It would be great if someone with original OEM bolts used at Metuchen around my build date can advise the IDs' for these. AMK has some of these but they are zinc plated. Does anyone know of reproductions of these P/N's with phosphate + oil? Please feel free to provide corrections and comments to the above. Any help is appreciated. Alan
