Got the transmission squared up and the angle right. Started on the crossmember pattern. For something as simple as this, it took about 3 hours and a stack of card board templates that I didn’t like before finally getting one I did.
I do think the seat brackets on my challenger seats are going to have to be cut down about 4 inches. May just order universal sliders to build off of and ditch the powered seat option. Powered seats would be awesome but it it’s simply too tall. Only gives me about 3/4 of an inch of head room. It’s that, or try and sink the floor 4 inches but that limits exhaust options.
