When I tightened up the perch nuts I found that the wishbone doesn't want to reach up to its designated spot on the bottom of the pan. I suppose I could raise it with a jack, but I'm not sure that's a good idea. Any comments from the experienced car assemblers?
I'm thinking that is normal. Your spring is not compressed. Instead of it bearing the weight of the car, it is being pulled down by the weight of the axle. I'll bet it comes a lot closer if you put the jack stands under the axle.
I agree with Hal. Once you put the weight of the car on the axle the wishbone with lift up to the pan. Is that your 15?

Doesn't look like a '15. It has 1922 or later spindles, spring perches, and wishbone.
It's the mostly '15. I'm keeping the under-axle wishbone setup that came with it.
Normally, you need to push it down and hold it with a 2x4 across the frame to keep it out of the way. Check to make sure you have the perches installed on the correct sides. There is a left and right.
Yeah, that does look like it just lower because there's no tension on the spring. It appears to line up with the socket.
If you blow up Steve's photo it does look like the perch is installed correctly. However, if the caster is not correct after the wishbone is connected and there is some weight on the axle, the wishbone may have to be bent to get the correct caster.

Yep, the bosses are back.
If the perches were backward, the axle would lean the other way and the wishbone would probably be too high.
Everything looks hunky-dory to me. Just use a 4x4 block of wood and a floor jack and lift it into position.
