It is a shame that such a quasi-perfect restoration is spoiled by front bumpers that are installed at an angle instead of dead horizontal. It is one of those things that once you see it, you can’t unsee it!!!
Yes the 360 engine is an evolution of the 355, while the 458 was entirely new. And NO, the bad vinyl covering on air bag cover appears on a few 360’s, but clearly not a universal problem, like the sticky was.
