I recently bought a 63 greenbrier I have it up to daily driver statis now to address the drivabillity on the Hwy . with a light 10 to 15 mph wind it wanders quite a bit . I have a caster camber gauge and it shows 1 degree castor near 0 camber ,will more castor help it stay in it's own lane , it steers very easy now

Check your toe in front and rear.
Caster will make the wheel want to return to center which helps.
What tires and how much pressure?

Try the rears at the max pressure on the sidewall. I can't remember how much lower to run the fronts. You may need to go to higher load range tires to get stiffer sidewalls. I went from your size to 215/65R15s on 7" wheels in the rear and it took all the crosswind gear out of a Greenbrier.
Couldn't tell you how much change a shim makes.

Most people only differ 2-4 psi F to R.

On the rear suspension.... Check it's Toe-in! 1/4-3/8" Otherwise they wander easily. Shims are on Trans X-member and REAR Mount must be loosened when adjusting.


Also... Rear CAMBER 1/2" in at top/ positive camber.... adjusted by spring length...

These things have the aerodynamics of a brick. It's going to wander in crosswinds.

Yup.

Between the chin spoiler and truck tires (for the stiff sidewalls), mine behaves much better. Food for thought.

Wrong, negative camber is when the tire is in towards the car at the top.

Positive camber is what I call tippy-toes, and it handles that way also, with the tires pointing out at the top.thumbs up

Now for the first lesson in wheel alignment:

The rear wheels steer the car and the front wheels correct the path. So, get the rear wheels in alignment FIRST. Then match the front to the rear.

The first set on my Greenbrier were passenger car tires. Mistake. After they wore out I bought a set of light truck rated tires. They were much better. After they wore out I switched to 17 inch custom wheels with 50 series tires and lowered the van 2+inches. Only a trace of reaction now even in strong crosswinds. Running 40 psi all around.
