How do i know if i should use the battery hold down bracket the attaches to the stud and then to the fender and thru apron. I believe i have the orig. fender and the hole is there,but the apron has been replaced so i have not drilled hole.
It seems the brket was hit or miss on the assemblyline. If it had the hole it was because it got the brkt if the hole isn't there then no brkt . it makes sense that the hole was put there during the installation of the brkt. There were more cars without the brkt then with. Since you are using the original fender and it has the hole you have a choice use it and no harm done and no questions or don't use it and have questions on what the hole was for and points deducted if ever entered in concours because it has the hole and no brkt. I hope this helps you make a informed decision.
I would think you need to find out if the hole is in the correct location for a battery bracket first. Do you have some measurements or a photo? I would hold off untill this has been confirmed with others that had one. [JMO]
I think Zinc Phosphate is the most appropriate and matches the j bolt and battery hold down nuts, but I have seen the brkt semi gloss black as well. I probably should qualify my last statement that the zinc phosphate would be more a personal touch from a workmanship stand point and not necessarily a historical stand point . The fact it matches the surrounding pieces makes it more consistent with it's surroundings and may in some eyes look better much like the natural valve covers matching the natural air cleaner lids even though I believe the majority of the lids were black wrinkle after they changed over from the sand cast process to the die cast or injection molded process. It matches. As I said previously I have seen them both ways but as a good friend reminded me probably way more the painted black way then the zinc phosphate way.
I think thefordshow makes a good point to first determine if the hole is in the right location.My car,#910 had the bracket for the battery hold down.My car is original paint and the screw for the bracket that goes to the fender apron does not go thru the fender.It is right beside the fender and thru the apron only.
Just a reminder that service parts are not always made the same or the same finish as assemblyline items but in this instance black was a correct finish for the brkt and the simple design did not change from assemblyline to service part like in other parts examples.
Here is a picture of the bracket in my car (#1547, SAAC survivor) so you can see where the hole goes.
The picture may be of a un restored original car but the un informed may want to use other aspects of the picture for reference and not know what part is untouch original and which part is NOT untouched original. The use of the seratted bottom locking nut is one thing and the green battery disconnect and battery (just in case someone is really clueless) are another. One of my pet peeves is the use of the wrong battery holddown hardware so I have included a picture of the correct nut with attached washer to show which one was supposed to be used . I see this wrong on the majority of restorations out there. The special nut with attached washer was used on 1967 to 1969 Shelby to secure the Battery hold down. The special nut was also used on Mustang ,Boss cars for those years as well. It has a attached washer which turns so when tightened it will not dig into the rubber coating of the holddown . The AMK kits include this special nut.
Good post, Bob. I would also like to point out that although some car manufacturers were installing battery felt washers by 1967 (ie Chevrolet), they were not being used by Ford/Shelby. I would hope everyone realizes that as this is not a restoration, but a a 43000 mile, 41 year old unrestored car, the battery has been replaced. I recommend use of a battery cutoff switch. They are actually a required judging item by some marques groups as a safety feature for an automobile. Looks like you’re right again, Bob. I took a closer look at those battery nuts when I pulled the car into the garage for the winter this past weekend and look what I found
