They're probably better than the POS Edelbrock trailing arms I had. The swivel bushings had the incorrect size hole for the bolt, thus rattled.
Plus, the zirk fittings were on the top of the TA facing backwards. This made it impossible to get a grease fitting on it. I had to use a needle fitting to get grease into them. The dolts at Edelbrock kept telling me, "Oh, our engineers designed them just for the H2." And i kept telling them, "No, they didn't." They're sitting in a box in my garage.
