Just checking in to see your progress so far. Keep up the good work. Lots of time/love goes into it.
Little bumpers? You mean the round rubbers on the top of the bolt used to adjust how far down the hood goes when you close the hood and will give slightly so no rattling noises ? That one?
The bar behind the bumper is to reinforce the bumper incase you hit something or want to use a jack to raise the car.
Ok Those are called bumper fillers. They fill the gap between the bumper and fender to giving you a more finished look and giving a space in case of a minor front end bump so the bumper will not damage the fender.
