73' B3 340 Duster pro touring build

I've been busy but it's hard to see big changes. lots of little thinks like brackets for throttle return springs, looks like no one makes one for a custom Indy Mod Man intake with EFI and dual throttle bodies.

The car is going to visit the EFI guy in a few weeks to dial in the Fuel injection. August is just around the corner, I gotta get moving.
