I just finished a customer car that bought a PST kit.
he had many wrong parts as his car was a 67/69/73 disc brake 69 Dart
So this consisted of total disassembly, clean and recondition, all parts, install new bushings and Ball Joints. Pitman arm, clearance header,
dismantle another correct Steering assembly for donor parts, waiting for correct parts, reinstall all
What do you think a fair price is for this service?
He agreed to $65 hours and I have 30 hours total including some wiring and e brake fixes.
Welcome to my world
Everything I bolded = extra time. Especially the clean and recondition part. I do not think you are out of line at all. Customers don't always understand the BS we go through trying to make things right, especially when it's a conglomeration of parts or Bubba's been there before you.
