Summit has $100.00 1" 5/8 tube with a true 3 bolt 3" collector for a mustang with a 302... We put them on my buddys car for a cheap upgrade over some shorties and they work and fit awesome..
You have to use the small ford factory starter though.
the summit 100 dollar headers I was impressed by as the quality for the money is great. they include everything u need. as for fitment on the said p heads they take a bit of massaging on the #4 primary (with a hammer)
