opinions..... front end rebuild

25 years ago a friend of mine had the front end rebuilt on his '71 Barracuda. As I recall the labor was $1,800. I rebuilt the front suspension on a '57 Dodge in 2018. I charged $750 and it took much longer than 6 hours due to some rust issues. $600 is a bargain. If I took another in I'd be at $1,000 for labor. I also charge $75 per control arm to replace bushings and upper ball joints and feel that's a bit low.
