- Insulated Fuse pullers (for home type main fuses, good for pulling running plug wires!)
- 5/8's and 13/16's Spark plug sockets (if your basic tool kit does not have them.)
- An inexpensive Hydraulic Floor jack.

This is the tool kit My Bro and I just outfitted my 17 Year old Nephew with To do his FIRST project Truck..a Frame off Dodge..
You can buy this stuff a little at a time , each payday, or splurge on the plastic..
Unless I forgot something (and I probably did..) this should see you through any project while you learn..The most important lesson..Take care of your tools , no matter how inexpensive they may be..someday, they will be the expensive brands..
Good Luck on your Project!
