Kingpin angle is one of those areas different people feel differently about. Some say 4-6 for Chevy spindles and 7-9 for Fords. For me 6-7 seems to work fine. Too much makes the car harder to turn, but can make it go straighter.............that is why you see dragsters with so much inclination, but why the wheels flop when turned, or backing up. I have gone as high as 9 degrees and didn't really see much difference than the 6-7, but that is where I start.
Yes, I already have my front tires and they are 25 inches in diameter, so my spindle will be at 12.5 inches. I like the rake I set the frame at, it is on about a 3 degree rake, so I will put my axle in place, calculate where the frame will rest when loaded, then make the holes for my wishbone tie rod ends at that level. Sometimes you luck out and hit it, and sometimes you do something to raise or lower the front to reset your kingpin inclination. I'm sure smarter people than me have a scientific method of figuring it out, but I just wing it.
As for the 4 link, that will be only on the back and will be hidden by the bedsides. Up front I am using a Speedway wishbone setup that looks like early Ford stuff. Fenders? We don't need no stinkin' fenders !
And just because you asked, I am posting a picture of Lucky Cat and me taking a little nap.
If we don't do this every afternoon he gets cranky.
