Also, the pinion angle can not be set properly until the springs can be loaded to normal ride height as it will change from the no-load condition. After proper pinion angle is determined, the caster angle must be checked and corrected, then you can worry about the steering. 3/8 inch around the bolt on your steering arm is all right, more would be better. However you do it, you should have the hole drilled close then reamed to a snug fit to the bolt you will be using to prevent wallowing in the hole. '75-'79 ford vans E100 & E150 w/PS used a steering arm with about 2" drop. Eng #D5UA-3590-CA. Stock arm will give you about the same 3/8" after reaming.
