yup, when i did my conversion, i got my brand new mopar box from wholesalemopar.com for around $25 while used ones were going for $40-$50, figure that out???? also for the gas 2nd gens, i believe you will need to relocate some emmissions stuff just a bit to make room for the box, but the box will bolt right in

 

I got 1/0 welding cable for my battery install
