For the engine bonnet hinge, I looked at Autpro and USMC butler build threads for some ideas, as well as some pictures of Murci-Me car.
I cut the old rusted inch tubing out. I took an Audi A-4 hinge and modified it so it would mount in the holes in the OEM replica engine bonnet.
Not sure if I'm going to try to create a more OEM look like Auto pros but will wait until the bat wings go in to figure what to do
