Antenna and floor soundproofing

The ‘proper’ antenna for the Chevy to replace the generic 3 part mast on the car.

First problem is that the tabs need to be bent inward for the antenna base to fit properly.

Here it is finally in place. The original setup didn’t allow enough treads to show above the fender to allow the big top nut to fit. In the end I had to use a dremel tool to cut the mounting plate grooves lower to allow the antenna base to rise farther up the hole in the fender. It should have been an easy fit, but as is often the case with aftermarket stuff the fit is bad. Also the parts book and some venders show a large ground plate of thin aluminum that should be mounted between the ground plate and the fender. No way I could have made that fit. As it is I was just able to get the big nut on the top to fix the antenna in place!

Getting the soundproofing in place. A real bear of a job getting in all the tight corner spots at the back. Lots of sharp edges so lots of scrapes and cuts.

Sorry for the poor image. This is the 120 mil product I’m using. One package covers about 30 sq. ft. that was enough to get the back done and the front sections of the foot wells. I plan to use it on the hood as well so I’ll need to order another package. The total will be about $200 by the time I’m done. Oh yes, not made in Russia, but in a country that used to be part of Russia – Kazakhstan.

Next: the engine block is back 🙂
