Speedometer Cable Question for 77 Chevy P/U

[77 ChevySport]

Have 77 Chevy P/U with the optional gauge package. Have a speedometer
that is now not working. (But did work) We recently replaced the cable and
it worked perfect. I am going through the connections (two piece) and checking the tightness of the connections.(Cable/Transmission/Speedo Gauge) Cable and transmission connections seem OK. I tried to stick my
hand behind the cluster to check the connection to the gauge and could
not find a way to get to the gauge. Maybe I just going in at the wrong angle.
Can one get to the gauge this way or does the cluster have to come out a bit to get to the gauge. Please advise and thanks if you know. Larry

Hi
follow the cable up and you need to push the nib to release the cable
some times it can prevent it from goiing on ,may need to jiggle it in /out
if you are removing the cluster
watch for the fiber cable for the ashtray light(on the left side here)
runs from the socket across to the ashtray,undo the socket

Do you know if I can get to the Speedometer Gauge back with my hand W/O pulling out the
cluster? Thanks;Larry

You sure can. Unhook the negative battery cable on the battery first. That way you don't cause any unwanted sparks. I just did mine on my 84. And I'm a 6' 4" 300 pounder.
Lay on your back by the pedals and reach up with your right hand on the side of the column closest to the door. Push the clip forward and the speedo pops off.
