I stumbled across these on Speedway Motors.They’re made for sbc engines mounted in an early Ford chassis, but as I looked them over I thought they just had to fit the AD frame and I was right! I was worried about the steering shaft but it clears with ease on my trial fit. They sell them ceramic coated or raw steel. You can see them here:
