5.9 magnum flywheel

I just went through a similar problem on a 98 half ton 5 speed. It originally came with a 318, but we changed over to a 360. The only parts store that offered a new flywheel for the 360 was autozone. I dont normally use them, but what they had was correct. You cant use a half ton as reference. Tell them its for a 3/4 ton, and they can get it. It was about 150.00.
