    Hello Ferrari chat family.
    Had a run in with a concrete chunk in the road and it damaged my front crossmember. The rectangle piece sheared off, but is easy to fabricate. The oval elliptical tube is bent in and I want to replace it, but the tube shape is proving harder to find. Have some local Ferrari restoration shops to reach out, to but thought I’d try hear too.
    Thanks in advance.

    See if an engineering shop can make the shape using a sheet of steel and a press

    Saw your inquiry about this in “Vintage” and would like to recommend proceeding cautiously.

    The oval tubing used in older Ferrari frames is not just generic re-shaped round stock and repairing your damaged chassis half-heartedly by sectioning will likely compromise its structural integrity and potentially have serious impact on cars value, should the effort be noticed in the future during a pre-purchase inspection.

    I’m not familiar with Mondials chassis structure, but to correctly/professionally repair something like this may require significantly more effort than most, including professional collision repair shops, realize.

    He will have to cut a section out to get the cross section profile and get a length made to shape, that will be fun.
    I cannot see welding in a part section being any good

    You can buy lengths of it from Superformance, they ship fast and reasonable

    Again, not all available oval tubes are created correctly.
    Comprehension and ability to differentiate can be (and often is) imperative.

    Just because something is offered by a popular (online) vendor and their listing claims it being “correct” or for a specific application, doesn’t necessarily mean it is.
    Interweb & many of its online (only) stores are littered with inaccurate/-correct information and based on my (limited) experiences/observations, bigger their selections grow, more wrought with inaccuracies they become.

    YMMV.

    I design build fabricate cars from 1900-1939, motorcycles from 1900-1948, aircraft and ocean going ships, 80’s Ferrari’s are the most simplest and terribly fabricated mild steel chassis’s I’ve ever seen and repaired, your over thinking it and I’m guessing zero experience, the oval tubing is all squashed for that particular Ferrari, for my chassis’s I had a manufacturer hydroform several hundred feet so I wouldn’t run out. You can see it in my latest build, way overkill but it’s to carry weight in the front end of the Ferrari

    VonBarron, yes that is burly. The smaller piece may do the job though. My worry on the superformance tube is it appears oval but not elliptical and I don’t want to order, ship, and find it’s a different shape. Rectangle tube would work too but would be obvious to a Ferrari tech that it’s not close to factory. Would you consider selling me the smaller piece to play with? I reached out to Dennison in Puyallup and they only Had scraps smaller then 1 ft. Thank you kindly PTGGDUDLEY 253.639.4000

    If you want the curved sharp piece pictured next to the chassis rails then you can have it, just to let you know, factory Ferrari tube would fit inside it, snug.

    "...80’s Ferrari’s are the most simplest and terribly fabricated mild steel chassis’s I’ve ever seen and repaired..."

    This enters my head every time when placing jackstands and working under mine....

    I don’t have much experience with ‘80s Ferrari or their chassis, but if they’re similar to those used in ‘60s/‘70s, which do appear quite simplistic and somewhat crudely constructed, they do seem to be fairly well thought out designs (and after 20+ years of already successfully using similar structures by that time, one would hope so) and the oval tubing used in their construction in my experience does not appear to be just any old round tubing pressed to (elliptical/oval) shape.

    As for lifting or placing supports (jack stands, etc), I wouldn’t recommend doing it directly on those very thin walled oval chassis tubes. They’re not designed or intended for that type of strain, There are more appropriate and much stronger areas, including specific jacking points intended for such.

    OTOH, YMMV.

    I mentioned it part tongue-in-cheek but still with gravity. I always try to have safety redundancies when working under cars with jack stands, especially when I hear things like the stuff mentioned above. Even jacking points can be compromised and may not be obvious from the outside.

    I definitely wouldn't jack on that oval tube but it ceases to amaze me the crackpot set-ups folks use to lift their cars. Surprised more people aren't squashed like bugs.
