Another trivial but important tip for buyers of secondhand parts.
I tried a series 1 aerial on my series 2 and it's different, the aerial plug is different, the S1 tube is fatter, thusly the screw on crome bit too and the angle of the grommets is heaps less. I mangled the S2 for the arial plug and fitted it, but the angle grommets FMU and it didnt two stage anymore. (notice that the plug surround on the S2 is yellow) With the slimmer tube they made the black outer grommet go through the panel to eliminate earthing / potential rust spot?
