Headers misalignment to body cut-outs

Hello all, I have a problem with the alignment of the headers to the body cutouts. I'd like to know how you guys managed to line the headers to the body holes. My setup shows that I have the driver side header way off high while the passenger side is acceptable. I don't want to make the hole bigger on the driver side as it would be like 1 3/4 inch bigger hole! The bottom of the body wraps around both floors perfect. The engine seems to be ligned up and level. Did you try or requested a replacement header from FFR? aren't they all the same anyways?

If i move the engine tranny around to try to line one side , the other will be off or they will both be off.

I need a solution, how did you solve this?

I had the same problem with the driver's side high and passenger side good. Ended up modifying the motor mounts so I could move them in (closer to the center of the engine) and allow the engine to drop lower in the "V" of the chassis mounts. The headers fit great now and my engine leans slightly - the driver side is a bit lower than the passenger side.

I just did exactly the same thing on Sunday...worked like a charm.

You MUST have the Elephant ears installed before you decide to cut anything. Cloco them in place then see how much trimming is needed.

I echo this comment...these panels reposition the body substantially.
Don't be afraid to enlarge the holes once you get to that point. Just don't take take it slow. I got my kit without the cutouts and found them easy to do. You'll most likely have a few areas to enhance openings like the windshield post holes so just mark them off and take a dremel to them.
Oh...if you didn't put the bulb seal down around the cockpit and on the engine compartment tubing it will lift the body a bit too.

Don't move the engine and tranny to the point the driveshaft isn't in proper alignment. What's proper depends on who you ask.... Pinion angle and u joint working angles is a large subjet and could be a vibration or worse.
It's better to rework the cutout than to have drivetrain misalignment. I used the Gas N stainless set and they didn't matchup with the FFR cutouts perfectly either. The right side was off the most but was easily corrected. At this point I realized nothing else has really fit without tweaking so why should I luck out now? Just another project on the project...
