Front end rebuild - what's it worth?

Yup, $750 is cheap... It's allot of hard dirty work... Doing stuff most guys turning wrenches today either don't want to do or don't know how to do...

And the next question, are you just blowing it apart & reassembling it?
Or would he want to pay more & have parts cleaning/blasted/painted/powder coated?

And do you have an alignment shop that knows these old cars?

Are you doing straight rebuild or adding a few tweaks to improve the car? Adding front discs? This would be the time to do that..

All upgrades should add to the cost, but not as much as going back & adding them later...
