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

[wheee!]

Bin there dun that!

Agreed.

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” ....

 

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

Now you guys are just showing off ...??

Stock rad clears the trimmed up rails nicely.  Aside: the stock rads sure are beefy.  Were they meant to serve as a structural brace?

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???
