Default Need a dimension off of LS7

I need the distance from the ouside to outside of the lower exhaust flanges at the near center mounting bolts on a LS7.

It would be the magenta line in the photo.

I'll look forward to your posting of the dimension. If possible get it at the outermost points, that being where the bosses are for the studs.

I would be satisfied with either, the flex style or the solid from '06. I didn't know of that until you informed me about the solid.

By the way, does GM sell the studs seperately in the exhaust flange of the manifold?

I'm missing four, and they are stainless.

28 inches out side to out side is about as close as I could measure without a plumbob on hand. I dont kno if they come seperate from the manifolds. I would be happy with either myself as the only ones I can find have the cats on them and they are still pricey.

Thanks for getting the measurement.

I'm going to have trouble making these work, the inside of my frame rails are 24".

I'll have to figure out something.


Let me know if you come up with a source for flanges. I could make a CAD drawing for a laser, but will save that for a last resort.
