[6pack] Negative battery cable?

Grant, in my opinion this would be a mistake. The grounding system on the 6 has 
to be top notch. Make sure you ground on both spots designed for this. There is 
some debate on where the lower point should be. Some say it is the same hole as 
the rear hoisting eye while some use the bell housing hole. The point on the 
firewall is obvious and a very important part of the system. Spend the money.
