Yes. It is all shown step-by-step here:

First I removed the stock fiberglass/composite battery tray, then made this "adapter bracket" out of aluminum. This bracket bolted to the factory battery tray mounting holes + added more holes for another bracket...
Then I used this store-bought bracket made for a PC680 (
West Coast Batteries HDB 680) and bolted it to the "adapter" bracket I made (above step). This used counter sunk bolts to flush mount the store bought bottom to my adapter bracket...
The adapter bracket I made kind of hung out in space so I made this support stand to bolt to the lower factory mounting hole...
This extra "stand" gave my adapter bracket 3 bolt holes to mount too (it is bolted under the 3rd hole, at the right, in the below pic)...
Then the store-bought bracket bolted in place...
Then the battery went in place....
Then the CNC top bracket bolted to the base assembly....
Viola!
I made this all with a band saw, drill, and a welder. Kind of ghetto but it is rock solid and has withstood years of abuse, plus I didn't have to drill a single hole into the car and it fit with the factory positive and negative cables. I can unbolt all of this and reinstall the stock bits in 5 minutes.
Cheers,
