I have an old toothpaste sized tube of Mopar "speedometer cable lubricant", but I can't read anything on the tube about the contents. It appears to be the consistency of a combination of Lubri-plate and Lithium grease, but maybe that's because of how old it is? Instructions say to pull the cable out of the sheath and wipe down the entire length with this 'cable lubricant' and then reinstall. Since I have no issues with the cable on my cars, I've not tried it on anything I own. I think I got it from my dad, who passed back in 2005, and it was old when he had it on his shelf in the garage. He also had an aerosol can of Mopar heat riser spray for loosening and lubricating the exhaust heat risers in chrysler products. I remember him using it on his 70 Sport Fury and 73 Plymouth Duster. I used the last of it on my G and now it's just for display on the shelf in the garage. He was also an advocate for using Marvel mystery oil in both the crankcase and occasionally in the gas tank of his old Mopars. I had an uncle who always used STP, but dad never went that route. Memories!
P.S.- Living in New England with salt and sand on the roads in winter, he would also save a pint or two of used motor oil to generously apply to the inner rear quarter panels and trunk extensions on his 56 and 63 Plymouths. The rest he used to kill the poison ivy growing on the rock wall along the edge of the property. ;-)

Hello All ,

I received an NOS cable assembly for the 64 300. It has correct rubber plug to seal into firewall.

In the past I hung it vertically and squirted Kroil down thru the sheathing and cable.

I can remove new cable and apply Lithium or Never Seize products.

What would be best for wire cable lubrication.

Merry Christmas and Happy Hanukkah to all.
