OzyDuster74 chassis connector questions!!

So lucky with this car, pulled the front guards off and zero rust behind them. Remember this car was a beater when i got it wasnt even drivable and never had a resto other than very bad crash repairs. I was expecting rust in this area for sure. Pretty much in factory condition, lot of sand blasting dust in there so good to remove that as have been sucking and blowing it from every hole in the car.

Back of guards to bare metal, acid wash and prime. Not sure if the guards had been off before, was odd as when bolts removed looked like the guards were glued on to the body with some kind of polyurethane. We are also re seam sealing the entire car as obviously its all been removed and also gone super brittle
