Hi all -- New to this forum and to Dakota's. My teenage son and I went half on a 2004 quad cab, RWD Dakota w/ 89k on the clock. It's in great shape. One thing we need to address, however, is the antenna. It is missing. All the pieces/parts are there except the mast, or antenna portion that sticks up from the antenna mount/base. When I looked in the hole of the base, I expected to see threads. But, I don't. I've replaced antenna's before with threaded ones that simply screw in to the existing base. What am I missing here? Thanks in advance!!!
