It seems to be the way to go for Mig + Aluminum.

Yes that is true for aluminum, absolutely.  (But not much Al in a Datsun frame rail ??)

True, but smoothing out an EFI intake might be a good place to TIG some AL or relocating the valve cover vent

    Agreed 100 percent.  MIG + 100% Argon = no beuno 

    Unless of course you are MIG brazing with Silicon Bronze, then you want 100% Argon.  You can get away with 75/25 mix but you get better control with straight Argon.

    So getting back to frame rails ...

    Without any c25 for the weekend, I was forced to play “Game of Clecos” ....FC45CA00-7A5F-4E43-9058-980DFEDDF3C6.jpeg

    Fitting this rail was much easier than the first one.  The jig really makes it simple to get everything in the proper alignment....

    Okay a little bit but Si/Bz is perfect for what you are doing right now,  joining thin ga metal without the heat warping.

    Wait, wait, wait...

    So the guy using a laser guided custom made body panels is telling someone else that they are showing off???    :blink:
