I'm trying to install a power antenna on a 71. I can't figure out how the bottom of the antenna attaches to the car. I am missing the bracket, but I would make one if I had a clue how the antenna is positioned in the quarter panel. I have searched and found some pics of power antennas with the brackets attached, but still having a problem picturing how it is installed.

There is a stud welded to the inboard side of the well about 2-3" down. A strap connects the bottom of the antenna to this stud. The strap was held in place with a wingnut. I have no idea where you would find a replacement wingnut.

I have a 280-maybe this will help, maybe not.

Edit: never mind, my photos won't help you.

Take a look at ebay item # 370643164502. It shows the stock original strap mounting bracket used on early cars. The picture shows this bracket attached upside down. It should extend down from the bottom of the antenna, and, as mentioned above, is secured to a threaded stud you should find by a wing nut.

With your antenna installed, I think you can fabricate this bracket by determining the correct bends and length to the stud. This bracket is secured to the bottom of the antenna with the correct size machine screw. If you google "Datsun 240z power antenna" you should find some pictures of a lime car with the antenna installed for

visual confirmation of how it is installed.

.

Hope this helps.

Thanks guys-i just went out and found that stud. No wonder I didn't see it earlier, it is way foward of the antenna. I wll google to find the bracket.

I have a extra one from my 71, sent you a PM

Dave

Dave,

thankyou for sending that bracket-but I still don't see how this antenna attaches. I can tune some triple Mikuni's , but this antenna is killing me!

The thing that throws me off is the angle the antenna must have to sit at to utilize the stud. Also the offset that is needed to clear the interior plastic panel. Someone want to make it even more simple for me. I did google the pics on the antenna.

The bracket for the 280z as shown above seems a better choose. The antenna that I have to put in the car looks identical to the original as far as mounting points, so I think I have the right antenna.

Maybe this ebay antenna might help? The bracket certainly looks different than the 280z model:

Hi,

My Z432's antenna,hope this helps.

madkaw: here is the bracket on mine, and how it goes in the car.

Dan

You guys are awesome! What the problem wind up being is that my antenna is a reproduction or a later year and the original bracket does not mount up with this antenna-(sorry Dave, but if I use the original broke one I will have the bracket thanks to you!) I managed to make a bracket to mount the antenna I have and got installed . Problem is the antenna worked twice and quit

Also the replacement antenna I have seems to missing some kind of grommet. With the antenna installed i could see day light around the mast-water would pour in there. The OEM antenna is definetly built better.

The pain with all this is that it is keeping me from finishing the interior install in the hatch area. I'm about ready to order a plain old antenna-non-retracting- and be done with it. Any suggestions??
