Bolt guru's try this one!
Ok on a 65 the JG manual say's the spare tire tub used 4 recessed 1/2" head 5/16 threaded black phosphate bolts with washers, the assbly manual shows , part# 9420825 for the spare tire tub bolts, ok if thats true that same part #9420825 is also used for the fuel line to frame clips, but we all know these are cad plated ,richard fortier has these in a ad of his in the driveline 5/16-18- 1/2 cad , am i missing something here how can this same part # be cad plated and black phosphate at the same time. and if the bolts were black were the washers also black?.......saddle up bolt lovers.

Hi Jim
How do know the fuel line clip to frame bolts are all cad?

Re: Bolt guru's try this one!
You know mike i should have phrased that a little different ,i figured that richard would know the correct plating, so i should have said as far as i know they are cad , i just went out to the garage and pulled two fuel line bolts and one brake line and none of them have a e headmark they all have a tiny D in the center with several circles aruond the D ,cleaned them up and they appear to be cad.JRComment

Hey Jim,
They were all black, for the tub and fuel lines.

Jim:
I am not a bolt and nut expert, but I am in the stage of a rebuild of an orignal car that I answer.
Here's what is/was used on my '65 April build .
Tire tub atachment bolts are cad plated, including washer 5/16-18 x .5 inch, 7/8 washer, no head markings.
(They were in good shape and I am reusing those with some cad paint)
I dug out the old fuel line clips and bolts and it is the same size as the tire tub,... (very rusty, no sign of any cad but am not sure) and it has a head marking with a very small "D" and three or four rings around it. I did not re- use these.Comment

Re: Bolt guru's try this one!
Jim --My 5 th edition reads slightly differently [... secured to frame by four black phosphate 1/2" hex-head bolts with integral washers]. No mention of head markings.
Pic below was of a previous post where the consensus seemed to indicate NO integral washers [I'll leave the black or cad finish to you experts]. These are off my early '65 tub.

Re: Bolt guru's try this one!
The midyear JG's that call for spare tire tub bolts with integral washers are consistently incorrect; 5/16" thread-cutting bolts with separate flat washers were used, as shown in Wayne's photo. A change recommendation has been submitted for the '67 JG.Comment

The originals from my June 67 tire tub (Mar, 1967 date markings)were just like in Wayne's picture with loose washers, black phosphate, but with "E" markings.Jerry Fuccillo

Re: Bolt guru's try this one!
Jim,
usually the washers were natural, bare steel.

Re: Bolt guru's try this one!
Whoa, Guys,
for judging purposes, we are placing way too much emphasis on these minute details.
"E" head marks were the most common, others were used.
The real key is the unique slightly rounded outer edges of the bolt head and when properly torqued there is no way to tell if the washers are integral or independent.
With 4 pages to fill out and usually 8-10 cars to judge, if this configuration, finish, installation and completeness appears at a glance to be TFP, an experienced judge will most likely strike a diagonal line through that box and move on.
