So I'm bolting the suspension back under the '73 and everything seems to be going just fine. When I crawl from underneath the car I see this gap between the aux. support and the rear control arm support (terminology?). It doesn't show anything there (seal) in the exploded views, but I can't imagine they'd leave a gap for all manner of crude to intrude on the torsion bar. Did I miss something?
Crappy camera, but the red area is the torsion bar.
