6-7 degrees Castor ( will need a mod to get there)
1-1.5 degrees Camber
1/8 toe

Do these seem right?

Caster look good. You can use aftermarket a-arms to get there (Porterbuilts lower 1" Forward arms will get you in that caster range w/a stock upper arm) or you can re-drill the hole for the locating dowell on the lower shafts to allow shifting them forward. I did the re-drill first then got the PB lowers.

Camber is +.5 from OE specs. Target -.5 (better handling).

1/8 total toe.
