Would anyone happen to know the thread size of the screw-in chrome knobs which hold the dashboard timber in place? Is the threaded rod cast into the knob or does it screw in? I don’t want to damage the knob! The one I have as a replacement has had the threaded rod cut at some stage and consequently isn’t quite long enough to reach the captive nut in the metal instrument panel.
I measure .183" diameter and about 32 threads per inch but not quite, so that makes it a 2BA x 1-1/8" long.
It looks to me like it’s all one piece, not a separate threaded rod screwed into the knob, which is surprising.
It looks as though it was made out one piece of steel then chromed.
I might have to buy some threaded 2BA rod, cut the old threaded section off, drill it out, then thread and fit the new bar. If only someone had a spare!
