The '67 Mustang chassis does look like a good fit. I'm using the chassis from the Mobius A/FX Comet for my "65 Falcon AWB project - might be worth looking into for your project. The stock Comet chassis might be better choice as the A/FX kit has the raised front suspension and your Maverick looks like it had a nose down stance.
I adapted the traction bars from the Revel T-Bolt kit.
