The roll cage construction has many faults, poor fit to the joints, no plates between the tubes and the body,. as noted earlier, tubes not aligned properly opposite ecah other and should be TIG welded not MIG. Less tha ideal.
fun fact: tig has the lowest penetration and should not be used for rollcage assembly. Mig has better penetration but stick has even better thats why they used to weld rollcages with stick back in the early days of motorsport
