Front end alignment after disk upgrade

[berlins]

I have a 67 Dart GT and I upgraded the front drum brakes with upper control arms and disk brakes from a 75 Dart Sport. My wheels stick out a little more
now than before which I knew about. When I go to get a wheel alignment - should they use the same numbers for caster/camber/tow as my original 67
had, or the numbers for a 75? I just called Midas and whoever I talked with
said it would cost more($125) because they have to do more adjustments
than normal. (don't know how you could adjust caster or camber on the 67
without one affecting the other but what do I know??) Now I think I'll just
take it to the place I bought the front tires from - I'm "assuming" I can use
the original alignment specs. Anyone know what the correct numbers should be?

the original alignment specs were for bias-plys.. Completely wrong for modern tires!

Also you should look into getting an alignment gauge and doing it yourself. I paid under $50 for mine shipped to my door.

It takes a while but you have more control over it.

I don't know why it should cost any more for '73 than '67 front end parts. The specs should be the same. This link will help.

BJK, You beat me to it!

I've used the front end alignment kit from Eastwood. It takes some practice but it works pretty well.

Do you have a tire store nearby that specializes in alignments? Look for a shop with a tech that is older and started aligning cars long before computer alignment machines. A good tech can align a car using his own specs so the car will drive correctly without wearing tires. The Midas shop apparently just sets
the toe-in and charges extra for caster/camber adjustments.

Here's the final alignment specs on my Demon.

Needs some rear end shims. Look at how far off the rear toe is...
