I found it easiest to place my hand behind the dash. Find the two hand nuts that come off easily and then push out the speedometer from the dash. Then remove the cable. Should be a 5 minute job.

Have u tried?
What appears to be your difficulty?

On my 71 it's a simple 2 minute job.

But be warned......I'm an grumpy old fart. I take no shit from people too lazy to do a preliminary search of the forum.
Nor do I appreciate wasting time providing suggestions towards a solution to then have you ignore them because you have to do some investigative work, in favour of a possible solution from a friend of a friend of a friend who once upon a time was a gardener with a shifting spanner and a set of pliers and somehow fixed their glowing ignition lamp with a piece of surgical tape, speck of moon dust and a rusty razor blade.

You get my drift?

To remove the thumb nuts, I have to remove the heater control that is below the speedo. I don't remember whether it is heat or vent control but I can't fit my fat hand behind the dash with it in place. To remove it, depress the little button in the knob and pull the knob off, then take off the nut and washer. Pull out the control device from behind the dash and presto, you will have plenty of room to remove the thumb nut (at least on one side).

Put a light glove on. Stick your hand up behind - follow the cable up. Grab the knurled nut. Summon your 'inner Hulk' and twist clockwise - looking at your imaginary fingers in front of you.
Otherwise do what others have suggested.



The secret to creativity is knowing how to hide your sources.

To the intelligent person, life appears infinitely mysterious, but the stupid have an answer for everything.

Day Dreamers, don't discourage them. That's where original thought comes from.

Some photos and pre-emptive protection learned by previous experience. The 5/8" nut is removed from the control and it is pushed through the metal support temporarily.
