just a couple updates. the trunk floor is now finished and only needs some paint and dynamat to be complete. the floor was raised a total of 3 3/4" and gives me a ton more ground clearance. i still need to attach the rear bumper and work out the fill tube, but i made sure not to raise it high enough to cause an issue.
this is the before pic
the after pic
this shows the amount of room between the tank and the watts. if you are running the fays2 kit, you will have plenty of room with this tank. although i raised it, i didnt move the tank back any. it would sit in the same spot if i had the stock floor. hector is making some new straps that are a little longer for my mounts.
this shows how the trunk floor was done. almost all the seams are full welded. the only ones that didnt get a solid bead were the filler panels on the sides. the bottom will be ground smooth before getting a bed liner product, but the top will be covered with upholstery
this is how i mounted the battery. the sheetmetal is reinforced so the bolts dont pull it up. the top bar was just a piece of aluminum and i routed the edges so they are now rounded over. once the bolts are tightened (i dont have them tightened here), the battery doesnt move at all.
