My car had a rear antenna.  It's been at the body shop having the rear 1/4's were replaced.  When the 1/4's were removed the antenna hole that was in the old fender was tossed without a mesurement.  Huh Now it's my job to find the correct location.  Anybody have the dementions and a photo I can pass on the the bodyman?

Thanks!  Joe

Its in the assembly manual, under RPO U73 page A1.  Its a 1.12" diameter hole, 114.25" back from the firewall, and 28.94" from the centerline of the car.  There is a .14" wide, by .12" long notch extending from the hole at a 165 degree angle ( about the 5 oclock position) from straight ahead (or 75 degrees from perpendicular to the cars centerline)

My L89 has factory rear antenna. Give me a couple days and I can get you some pics with a tape measure so the body guy can understand.

Here are pics. Hooking a tape measure on the lip at the back of the 1/4 panel it is right at 15" to the center of the antenna. Looks off in the pic but the camera was at a angle. Hooking the tape on the trunk lip it was right at 1 7/8" from the trunk lip to center of antenna.

Wow, that looks awfully far back on the fender.  I had one on a 68 eons ago and it seems (from memory) it was alot closer to the corner of the trunklid like right at the end of the trunk corner radius (about 3" forward of the one in these pictures).  Since I don't think I've ever seen a real one on a 69 are the 68s in a different location than the 69s?

I just went out and measured my car (I don't have a read antenna) and found the the 110.25" measurment referenced in the AIM places places the antenna just at the end of the arc of the trunklid opening.  I measured 100 " back from my front antenna (The AIM says it is 10" behind the firewall- or the 0 reference point) and the point ended up just about at the rear edge of the arc (plus or minus 1/4") and the rear edge of the top of the quarter panel was 119" back (or 129" back from the 0 point).  Looks like the antenna is supposed to be located 19" forward of the rear edge of the quarter, assuming the AIM dimensions are correct.

Mine is aprox 14" to 14 1/2" from the end of the quarter panel. Hard to tell for sure with the antenna still on it, and  aprox 2" from the inside edge of the trunk lid. Very similar to the pictures posted. Also if it were to be 19" or so from the end of the quarter panel you would have little or no contact with a spoiler, which is why I thought you couldn't have both options from the factory.

The car I took the pics of is a 17000 mile car with manual rear antenna listed on the orig window sticker. It was repainted once by the orig owner. Orig 1/4 and antenna hole.

Had a math error, the AIM says 114.25" back from the 0 point not 110", so a position 15" forward from the rear edge of the quarter, or 4" back from the rear end of the trunk lid opening arc is correct.  Still seems like it moved from 68 to 69 (or my memory is bad) .  Anyone have a 68 with a rear mounted antenna that they can measure?

Mine were from my 68, I guess I didn't look at the year of the car in the original post

Hey Charley!
Thanks so much for all the effort!  Kiss  That was the greatest help.  Looks right from memory, (trying to remember the old fender).  As long as with the antenna all the way up the spoiler hits it with the lid up I'd say I'm back in business.  I printed the photos for the tin knocker. Roll Eyes

Thanks again for the help!!
