DISCLAIMER: I cannot stress enough that what works for me may not be what works best for everyone. This is a “take it or leave it” thing!
… because DIYers know that keeping everything that you might have a use for later is one of the first steps to keeping costs down.
If you’re down to the point that your car is only good for the scrapyard, don’t crush it yet, there’s a lot of random parts that can potentially be re-used on another car or future project! I’ve realized this my first time out and accumulated a lot of hoses, tubing, wires, fuses, screws, and bolts from my STi and various past projects.
It doesn’t look like much but I assure you that this is about $150~200 worth of tubing! They can be expensive depending on where you live. Don’t forget to keep your trimmings for the smaller tubing! Why? Because for the moments when you’ll go “it’s not long enough!”, you can simply buy super cheap PEX connectors at your local hardware store and rig same size hoses together! Don’t forget to keep those old clamps too!
After modifying my rear bumper this panel was left:
Throw that in the garbage, will ya? Wait! What does it look like to you? A gauge cluster maybe? My yes it does! In the box you go!
If you cut sheet metal, you can also store away the unused pieces of decent size in a bin, and the smaller pieces in a jar.
You can use them in future fabrication projects. The smaller pieces can also work great when trying to fill a gap when MIG welding. If you TIG weld, they can also be used as filling material if properly removed of paint.
