Save us some headache - Glance at our cage (Pics O Plenty)

Everything looks pretty good.
Can you show a better pic or two of the rear hoop and diagonal.
That looks suspect.

I'm no cage expert, so I'll leave the opinions to the pros.  I will say nice (snicker) choice of car (snicker, snicker).  From the original color, I'd guess around a '72?  Welcome to hell.  It looks like your battery box/firewall was pretty far gone.  We had to scrap our first car for unrepairable rot in the RH firewall.

It looks like you got the seat pretty low.  Ours is way too high.  Otherwise, your design is very similar to ours.  We added a diagonal roof bar from the LH A pillar to the RH side of the main hoop.  It gave us extra height in the cage.

WTF is this?

no way in hell I'd ride in that car with welding like that. I don't mean to offend you, but I do encourage you to replace that tube at bare minimum.

Looks like a shielding gas or oxy tank in the background...MIG is good but it's easy to get welds with poor penetration, oxy/acy is expensive, but stick welding still works well for me....easy to get penetration and unless working overhead, good control and cheap...these look like arc welds with lots of overlay, maybe concealing slag/voids. Might still be plenty strong, but a gusset or two probably wouldn't hurt...

From the height of the tank in the back, it looks like an 80ft^3 C25.  It's not exaclty hobby size, so someone knows what they are doing with a MIG. 

The actual weld on that corner doesn't look bad - from the picture, it looks like it penetrated and doesn't look like there is undercutting on the tubes.  But there is entirely too much fill.  If you are not going to replace the tube, throw a big ass thick gusset with good welds on that corner and hope that tech likes it. 

I know that you are already tied into your door and dash bars, but if you were going to replace that tube - you can cut it above the dash bar and sleeve it along the A-pillar.  It shouldn't be that hard to replace.  Of course getting a 360 weld on the top will require you to cut the roof... 

Jim, oxy/acy is fairly cheap.  I only pay ~$70 to get both of my big tanks filled.  I would NEVER oxy/acy a cage.  It is too easy to f-up since you don't have the easy of heat control of a TIG.

Get some rustoleum on that shit ASAP.  All of it, bars and welds.

No we use a notcher and the cage fit tight. The guy that welded it just thinks more it better.
I think he said he put 7 or 8 passes on some welds with cross stitch.
Weld on a weld just adds weight, we tried to explain but he still does it.
Hopefull it will pass, I don't think I can afford enough grinder wheels to clean that up.

Thanks for the input guys.

Just take a peek at any structural steel bridges/refinery stuff. Multi pass welds.

Those welds scare me: as an inspector, all I think when I see welds like that is poor fit and no penetration.    I would have to inspect those welds with a mirror and penetrant to be happy with them...   Which event are you prepping for?

NASA allow the bar to be within 12" of the corner and the SCCA allows it to be halfway along the top.   

They are close to 45* on the cage.  The main hoop is not vertical so it's a little hard to see.  The SCCA allows rear stays to be 30*. 

Not a big deal.  Having them in the same line is great for force transference - but as long as they are close it still works.  I'd start to get concerned when they are getting about 12" away from each other.
