Dwight, I do weld some seams on the cars I build but I stich weld them .
The key is not overpenetrating the seam and burning thru or undercutting.
I agree on a car like a Nova that is inherently weak in some areas it will help to weld a seam here and there on the front end ,especially since many of them are already pulling apart from years of use [and abuse] , but I feel the roll cage for a car like this is still the best solution.
I have done several cars with weak front end mountings for Stock Eliminator ,early Mustangs ,Dusters ,AMX's and Novas and have welded plates to the driver compartment side of the firewall at the point of attachment for the front end and run a tube to the forward leg of the cage to tie it in.
This is legal for Stock and has been accepted on all the cars it was done on.
