I contacted him( Mark at Mad dog ) regarding headers for my 64 Galaxie, it was either him or Crites, after finding all the negative reviews about Crites customer service,I decided to go with Mad Dog.My Galaxie has power steering and a z bar for the clutch, so I knew I was not going to get them off of Jegs or Summits shelf.Anyway after about 5 weeks, and a follow-up phone call,they were sitting on my front porch when I got home from work. They fit perfectly, no hammer need ed, only mod I needed to do was relocate the oil filter, the header tube was so close to the filter, the heat was cooking the oil. But they look awesome.
