i took apart my dash to get to the lights behind the gauges.

taking it apart and putting it back together was easy but think i realized i put

something in wrong because it didnt turn the gauge lights on right away and now sounds like this ...

if this video doesn't work its making a clacking sound and goes faster with the acceleration would something i plugged in wrong or bulb put in wrong make it start the clacking sound IDK...

 

why on coreys amazing YT would you make 2 threads?

 

lol idk cuz im weird.

 

Or just disrespectful of the rules...

Again, Check your speedo cable that its plugged in all the way, or you may just need a new one...

 

Speedo cable.. Make sure its plugged in all the way, shoot some grease into it. If it goes away (temp fix) then buy a new cable.

 

I had to get a new cable for my 85. The heat of the Exhaust Manifold cooked the housing around it, allowing it to contact the wires within the housing material and making a really nasty Grinding/rubbing sound. But is sounds like you just didn't get the speedo cable plugged back in all the way.
A way to test that without taking the entire dash apart again would be: Disconnect the speedo cable from the tranny and drive it. If the noise goes away, then you've probably found the issue. : )

Good Luck!
