I got the pieces for the Checker’s battery box from sendcutsend earlier this week. Laser cut out of 1/8″ Stainless. Everything fit together really well and was easy to get it tacked together with the tig welder as the tolerance and fitment of the panels was really good.
And here is the test fit inside the trunk of the Checker. Still need to finish that rust repair before I can install this :)
