When I was younger I could do a complete front suspension rebuild like that in about 8 to 10 hours. ( not so sure I could do it that fast now though )

Its when you get into cleaning A arms and torsion bars and strut rods etc etc is where a lot of time can be tied up QUICKLY. So I could easily see 20 hours plus in that kind of time in the job
IMO, I wouldn't touch a front end rebuild like that for less than $1000 plus parts

Wiring is something I HATE to quote ahead of time. Most people have no idea how fast time can go by when chasing electrical gremlins
