Doug's Header - Clearance on Driver's side
I recently put my freshened up 400 back in my LeMans with a set of D590C - Doug's headers. I'm having an issue with the headers knocking on the frame at idle on the driver's side. Is anyone aware of a way to space or shim the motor mount to give me an extra 1/4" or so. That should do it. I can't imagine I'm the only guy with this problem.
Thanks for the help. -Scott-

I had to loosen the motor mounts shift the motor over. Tighten the headers then tighten up the mounts again. No knocking.
