Default Speedo cable / Tach Cable Question

On my upcoming dash reinstall, I was wondering about the possibility of detaching the cables from the distributor and manual transmission, thereby gaining some slack for the driver's pad install and then gently removing slack once I re attach the cables to the dist. and tranny.

Is this advisable?

I have a lift so getting it up to get to tranny is simple.

Not only is it advisable, it's a good idea. You can also detach them from the back of the gauges (attaching clip). You can inspect the tranny and distributor cable ends for any wear/damage to the squared-off ends. You can also inspect the speedo drive gear in the tranny for any wear/damage in the 'socket' to which that cable is engaged. You should also remove the brass coupling on the side of the distributor and inspect the output gear that meshes with the distributor shaft drive gear; if there are brass shavings/debris on that component, there is excessive wear that needs to be addressed.

The cables can then be drawn out of the cable sheaths from the gauge head ends. These can be inspected for damage/wear, also, and can be lightly lubricated with graphite for smoother operation. Do not put grease or heavy oil on them as that will eventually cause the cables to bind up.
