If you want to drive a finished product, buy everything that DF offers and you want. It works and bolts in without fabrication. I see a lot of people get bogged down in the weeds trying to fabricate something that took me just a few minutes to bolt in. I was driving mine within 4 months of starting. A 1/4 to 1/3 of that was the wiring harness. There are many people here that will never finish their Goblin. I think because they try to customize everything and loose interest before it is complete. The Doyle family are engineers by trade... They have already done the job for you. It is an awesome kit.
