I was considering having my existing seats recovered and modified to accommodate the Sub strap on my 5 point harnesses, but started thinking about how ill fitting they are width-wise.
Sprung for a set of Ultra-Shield Cobra Buckets in Black. They have the Sub slot provisions already.
Should be 4.5" wider in the hip area than what I have and 2.0" narrower externally than the current seat. (Alum frame is thinner than the factory fiberglass bucket).
Should be 3 weeks for arrival. Free shipping at least.
