Sox and Martin replica

Hi folks,
Just got myself a stripped out Duster shell.

I have a pile of B-body front suspension and no later A-body.

Is it possible to retro fit B-body upper and lower arms with disc brake spindles?

Or as its gonna be a track car just go for a front A100 beam axle?

What front suspension did they run, back in the day???

Many thanx for any info from John
