1995 Chevy Truck short in gauges fuse

Electrical problem
1995 Chevy Truck V8 Four Wheel Drive Automatic

in our most recent snow storm I got into a crash trying to avoid another car spinning out. I hit a concrete pillar head on which broke the bumper in the middle and smashed my grill. But other than that nothing appeared to be wrong. No fluids leaking, shifting fine, etc.
several days later, I was driving down a rough road and hit a pothole, instantly my battery gauge and speedometer stopped working, and of course since the speedometer stopped working the transmission wont shift. I found the gauges fuse popped, and replaced it. After which everything started working fine for a couple days, then it popped again, and now pops instantly when I replace it and turn the key. I can't seem to find the short anywhere.
Also, today I started the truck and pulled it forward, which worked fine, though still not shifting out of first, but when I put it in reverse, the engine died after several seconds, this is the first time that has happened. Could this also be related to the wiring short? And any idea where I might find said short? Thanks for you help!
