How many ground/return Amps are you trying to carry?

Try a welding supply place. Fine stranded very flexible welding/grounding cable usually cut by the foot. Get solder-on eyelets and a lb of resin core solder and make your own
I am going to make the grounding harness that runs the generator, body, starter, and pcb? Box, to the engine ground.

Also call local car-audio installers. All of the good ones keep 500ft rolls of every gauge for grounding all sorts of things. They WILL sell you cut-to-length(dont expect exact) for a reasonable price.
It's the 4 wire grounding kit from Kascar:

I already have the 12 gauge wire because it's all I could find. I just need to know if 12 gauge will work or should I return it and look for 10 gauge.

EEEKK!!! That needs to be MUCH larger than 12Ga/10Ga. The generator (alternator, 100Amps), and starter (up to 1500Amps) will ground through the engine, but steel has about 10% the conductivity of copper (and power has to jump through gaskets and bolts). From the negative post of the low 12V battery, go with a 2 gauge or thicker wire to the alternator, 0 gauge to the starter, and 8-10 gauge to the engine block itself and another 8-10 gauge for the PCB (where all the power for the rest of the chassis splits from).
I think I may have been a little muddy in explaining what I want to do. That's my fault. I want to make the harness that kascar sells and everyone recommends installing. I have seen how to make it explained on flashoffroad but I think he uses 8 or 10 gauge wire. I'm not replacing any existing wires. I just want the mentioned grounds grounded to the back of the engine like the kit is supposed to. I could just buy the premade kit but I can't spend the $70 right now. This is a cheaper option right now.

I just think skimping on grounding will result in a fire. But thats just my opinion...
I do too. That's why I want to make sure I use the correct gauge. I'm pretty sure in the post "glow plug gospel" even mentioned making your own. I just want to make sure I'm doing it right.

Jeeeze...thank you Ted....just buy the harness from kascar, no fuss, all done.
i used to make mine, while maybe at 1/2 the cost...but my time is worth more then the 40.00 I saved.

"RF bonding" bonding? Should be a wide/flat strap if so.
There is some good info on this link for your installation. I'm not positive but I wouldn't think using 12 instead of 10 would be a big deal on this application. http://www.hummerknowledgebase.com/electric/hghi.pdf
