I started today cutting and welding. The idea behind their AGM design is that the battery can be mounted in almost any way except inverted. So I decided to use that to my advantage. I'll be building a battery rack in place of the stock battery tray and will mount one there as it usually is. I Decided to put the second battery on the passenger side and will be mounted on it's side. So far i only have the passenger side backet fabbed up but the driver side will come later this week.

Started on the Driver side- I've been wanting to trash the stock battery tray for years and I now I can. Pulled it out and made the frame for the tray. I'll work on the supports tomorrow.

Been Busy but today I had some spare time to start the sheet metal around the battery boxes and engine bay. I am building these so they can easily be taken out if need be.

Put in a couple more hours of fab work today. Slowly comming along. Wish I had a Metal Brake -Would have made doing this alot easier, Instead I'm cutting out my panels using a plasma cutter, getting as close to my line as possible without burning through it and then grinding all my edges straight. This is what takes the most time. I'm also trying to keep both sides some what uniform so it's easier on the eye's.
