with your wings just do like me and bolt them on it'll be so much better in the long run, just as strong and if your ever to bump them or doing an engine swap you can just take them off and yea most your panels will need spot welding on you can hire one if you feel brave just have a few practice welds first to get the strength right, and with mig welding well i can't weld but getting a crash course at work so will let you no from a beginers point of view
