Missing captive nut for battery hold down?

[SoCal_Lynch]

Hello - hope it’s been a good weekend for everyone.

This is a 1970 911 that seems to be missing a captive nut, is that right?

Time to weld a new one in place or others ideas on getting a battery hood down mounting point (for the bracket that immobilizes the battery) secured?

Thanks

Maybe a Nutsert but it doesn't look like you have enough clearance for it to fit.

Better idea. You could drill a second hole very close to the original and then buy a universal hold down that has a "J" formed on one end. Loop it thru both holes.

Where did it go? I’d run a camera/bore scope in that hole and see how bad it is. Might be time for a suspension pan. At least run some fluid gold or cosmoline or whatever waxy/oily rust prevention measure thru that cavity. And then a rivnut or similar would be a good fix.

Nutsert would be a god idea.

That said…..thats an area of BAD rust in these cars. If the nut vanished find out why. If there is rust in there then your front suspension mounts are at risk. Best to know whats in there. I am just finishing up a suspension pan replacement in my 1975 911S. I found more air and bondo than metal under my battery tray.

Rivnut.

I'm running Braid's that I had custom made. While picking sizes Paul from Braid did a video call with me to make sure I was measuring my car right. Apparently I have unusually wide steel front fenders. My fronts are 17x9 -9 offset, rears are 17x10.5 -45 offset. My tires are 245 front and 275 rear, from memory. The car is currently cut apart for rust repair.

I also removed ALL of the spacers that are normally present on wide body converted cars. It's all in the dish on my wheels.
