Hi
How much should the difference be rear and front of the wheel?
I read in the Chevrolet manual and they says 0 to 1/8" taken from the metal rim.
If I take the distance in the center of the wheel (rear and front) and the rod have the shortest length I got 1"

Basically for the front wheel tie rod adjustment you are measuring to ensure that the front and the rear measurement for the wheels are 0 to 1/8 inch difference, which to me is parallel. With the play in these old mechanical parts I don't think 1/8" can be maintained. If they look right and the car drives straight I would leave it alone. After all this is a low speed vehicle. I adjusted my wheels with both wheels off the ground using 6 foot pointer sticks attached to both wheels. I aligned them so that they were parallel to each other.
My 2 cents.
BTW, Camber and caster is set by the King Pin Axle. I don't believe that this is adjustable but I might be wrong.
Jjohn something does not sound right . One inch diff with short being back is way out and pigeon toed . Car should be done on ground and positive toe in ( front shortest ) by about 1/8" . I measure with tape rule off a middle thread . Easier for one person , then metal rim and accurate enough . Yes this small eighth made my truck stop most of it dancing on straight away driving .
Tom, I agree that if a difference is to be had, the front should be shorter. But really 1/8" on a 20" wood wheel is a tight tolerance to maintain. Once the car rolls 10 feet past the first turn I would bet $$ to donuts that the dimensional difference would change. But I guess something to strive for. The adjustment in the Plymouth instruction book is pretty specific and once marked the same point is used for the dimension. The book also mentions using the felloe which is the metal ring the spokes attach to.
This is from the Chevrolet manual 1928
Same same for the Plymouth.
