[Spits] screw-on battery terminals?

[s1500]

My Spit's battery finally bit the dust yesterday. After an attempted 
charging, it's not going to turn the starter motor over. I double 
checked the battery terminals, etc.

My question is this: How hard is it to use those newer type screw-on 
battery terminal posts with a Spit? Finding the positive cable 
replacement should be easy(it's a small cable), but I have found zero 
luck in finding a battery cable that also branches out to the ground so 
it ground out to the tranny bellhousing. Unless there's some separate 
cable I can mount on the screw terminal thing to use that for ground. If 
that's a no-no, please tell me.

I've realized that these old fashioned battery clamps are more of a 
hassle than anything.

Also, would this get in the way of the factory standard battery 
hold-down clamp?
