I had some on my '72 Duster...Long story short, had Hedmans, wrecked the car, bought new car, swapped motors, Hedmans were trashed, in a pinch so grabbed the Doug's. They worked OK, I guess. Fairly cheap construction, not overly impressed with the welds, tube thickness, etc. When I pulled the engine the last time I pitched 'em; they were rusted through in spots and the torsion bar wraparound was now one piece and had to be cut off. Will I buy them for this build? Doubtful. But if you're looking for cheap & fast, go for it.
