Hello,
I recently replaced my gauge cluster back with a new one from jeffs bronco graveyard. I had the old one setting around and decided to run it over with my truck, because what fun is it just throwing stuff away.

The truck is a 78 f250 with a 460 c6 2wd to give you a idea on the weight going onto the backing plate.
Here is the video i made while it was crushed.

Heres whats left

 

Hah! That's funny. I'm assuming the old one was in useable.

 

Mine kind of did that all on its own.

 

I've got a spare cluster that's been on a shelf since 1987 ..... I recently took it down and unwrapped it to look at bulb holders and maybe try some LEDs in a dark basement, it too is decayimng, crumbly like. Afraid to even touch one in truck now ....
