My attempt at installing a LOKKA brand Auto locker

[Bigrig]

If you don't do this yourself how much is a reasonable amount for a mechanic to charge? i was quoted $600 and there is no way i am paying that. I'm good with building stuff with wood but am almost mechanically retarded excepting general vehicle maintenance

No way mate, it's a $200-300 job with someone who knows what they're doing ... 3-4 hours.

Where are you based? We could recommend some places.
