Looking good dude, reminds me of when i did my bumper on the '99, card board and tape. I think i had close to 16 hours in mine start to finish, making bumpers out of plate takes a lot of time. When i made the tube bumper it only took 3 hours start to finish including the cardboard mockup build.
All this bumper building going on makes me wanna build the last four that i have to build.
