Quote from Boy from Oz
"Change of topic, but very relevant to 250 GTO with twin REAR exhaust. Zerrari - I noticed elsewhere that you have, or intend to make, a front diff mount for twin exhaust. I am about to do the same. I have noticed this done elsewhere on HybridZ but it worried me that the two mounts had (apparently) been cut in a straight cross section in the middle and then welded. I think it might be a bit more structurally sound to stagger the section, the way A-pillars are cut and joined in a 'cut & shut". Any thoughts."
Boy from Oz,
To make the front diff mount fit you really need to cut a section out of one of them and then splice in the rounded part from another. This keeps one of the mounts pretty much intact. You could do this with one mount and cut out a section of steel pipe for the other rounded exhaust section.
Once you have two mounts side by side you realize the way the mount fits is not symetrical so you can't simply cut them down the center and weld them together.
