    Don’t trust receiving tractor supply items on time

    8 days ago
    Only recieved part of orders I also ordered a t oss gasket. The gasket isn’t even listed on the website anymore and still says delayed in my account. It’s been two weeks. I called and they can’t give me any info. My suggestion but direct from Mossimo and pay shipping if you don’t quality for free shipping. I can’t put the thermostat in until I receive the gasket so I can put the header back togeather, it’s been ripped apart taking up my garage all this time. shm. Just my opinion but do what you want. Terrible customer service told me ship date was the date I was supposed to receive it at the store. Just told me what I wanted to hear and went about there day…

    No, I do not recommend this product.
