Peterbilt 378/379 Frame Horn R&R

Well about a month ago my dumb truck driver (Me) hit a foot and half tall concrete retaining wall and broke off the two tabs where the bumper bolts to on the drivers side. Now my mechanic (Me also) has got a good takeoff frame horn, new bolts and bumper and a day to do this. Should I be able to get this done in one day myself or wait for a weekend where I'm not working Saturday and have 2 days to do this on my own? Didn't crack anything relating to the steering so this is 100% cosmetic. I even got DOT'ed today so I know I'm good on the safety side of things. I just hate to get myself in a situation where I might be down when I'm supposed to be working cause I bit off too big a project with too little time. Thanks for any advise / words of wisdom.


In my own defense it was a bad job dumping around a rat's nest of overhead powerlines, was watching my spotter and as I dumped the load out and got my bed back down the wall got his under the hood. Probably wouldn't have happened if I was in the T800!
