I ordered a set of headers for my Bronco on June 21, still waiting for them, I called the manufacturer after getting excuses from the retailer, and yes, there is a backlog in manufacturing.
Figures, Had the same problem with my Scamp bucket seats and when I got them they sent me 2 left seats. They wanted one back before they sent me a right one but about 3 months out. Screw that I made it work and yea pisses me off.
