I went to a battery shop today and found a dead donor for my mod.It's a newer Chevy version so it will be easy to get when it comes time to bolt the new one in.
I made the rear mounts out of some scrap laying around the shop.I'm always glad I kept the small stuff,beats going to the local steel yard and wasting time.
The plastic block,Chevy as well.Had to modify it front and back to make it fit, now holds the battery tightly in place.
