caster camber & toe
HELP!, I can not find any info anywhere about what the caster, camber and toe in degrees should be for my 1937 Plymouth business coupe. The car wanders continually down the road. I always have to correct. Steering is tight but the wandering is driving me crazy!
Does anyone know the answer? If not, where can I go to get the answer.
There should be a minimum, maximum and a preferred for each function.
Please help!

Can't help you on settings, but negative castor and/or toe-out will cause the problems you describe.

any changes ?
Is the Car stock ? you should be able to find original specs on a mopar resto forum. Is it the tubular axle or an IFS system.? I have had problems with tires wider than stock and a lot of offset in the rims. stock wheels and tires were OK, If you have raked the car, little tires in front, big rears it will change the actual effective castor angle.

caster camber toe
No, the car is streetrod, built 383, 430 HP, front tires are wider and shorter than stock.
Mustang II front front end, rear tires stock height but much wider.
Any advice anyone can share would be great!

The OE specs wont help.
You should have 5-7 degrees caster, no camber (zero) or a little + less then 1 degree, and 1/8 inch of toe in.

I agree with most of what latech said except the toe I'd find a reputable alignment shop and have them set everything while i was sitting in it and the toe I would have set to zero that way when you are driving it it is tuned to your weight.

Yes, if you have a dummy weight to put in the car as the algnment is being done , that could help the outcome.
1/8 inch is standard on a lot of vehicles. Many newer vehicles, maybe not. More like .100 of an inch.
As the car goes down the road , suspension loads, and toe in changes slightly.The tire will tend to fold back, or apart in the front, which is why a little toe in is generally required, or desired. 1/8 of an inch is only 1/16 difference from front to back through the center verticle axis of the wheel/tire. almost negligible.Unless you factor a little for suspension "loading". That tends to zero the small amount of toe.

Lower A arms
The lower A arms should be parallel to the ground front to back and side to side. since this was a suspension swap the angles might not be right, also mustang II take less pump pressure than GM std pumps you can buy a shim kit for the pump to drop the pressure.

Thanks guys, it's nice to have a guru or 2 in your pocket.
The info you all related will be dialed in tomorrow.
If nothing else it will give me a base line to start and adjust from. Sorry bout the caps, this ole laptop is stuck on caps lock.
I'll test drive after the adjustments and let you all know.
Thanks again!
