On my 55 2nd I bought the chevrolet fender mount antenna from Autozone and used the template I received from Squeeze. It didn't need the supporting bracket that bolts on below. I have had numerous decorations on the tip of it and it has not come loose. The unfortunate part in the TF trucks is that the antenna hole is between the outer and inner fender. Unlike the AD where your antenna is under the dash. I am glad that I have skinney arms - not big like popeye.
I hope you have good speakers or wear headphones.
