I also started the battery mount. I plan on mounting it on the frame under the passenger seat. The 1x3 channel will be welded to the frame with all thread welded to it where the bolts are. The tray will bolt up to it from the bottom.
I also am working on wiring the electric C6 door handles. I had to join a corvette forum to get the wiring schematics. They were very helpful. Think I have everything coming this week to get it done. Next is to buy my hp tuners software and run enough exhaust to install o2 sensors. Then I may be able to finally start it
