Default Confirmed GMPP LS7 fuel rails

After talking with everyone I could think of, that might know the answer, in the industry, I have finally confirmed the answer.
The question was, what fuel rails will bolt on to a GMPP LS7 single plane efi intake (part number 25534413)??? No one could give me the answer I wanted. Most said they just did custom rails with welded brackets.
I wanted a bolt on part, for a clean look. So I did not have to weld brackets on the runners like I did with my L92 GMPP.
So with some help from Nineball (thanks Tony!), he sent me the stock LS7 rail assembly from his 09 ZO6. I was able to fit the injectors, and all the bolt holes lined up perfectly.
I will order Aeromotive LS7 rails, they come with lower injector o-rings, and taller brackets to work with the bosch style injectors I have.
Bolt on deal, anodized red, and capable of 3000 hp.

So, for anyone crossing this road, the aftermarket LS7 rails will work with proper spacers and orings on the GMPP LS7 EFI single plane.

How did you make the stock rail fit? Did you cut it up just to check and see fitment?

No with the tall bosch injectors it cleared the carb inlet no problem. All of theis was to confirm rail bolt pattern.
