I am planning a SAS on my 90 yota and would like some input on axles. I know the best are the 85 with the stock upper truss, however i aquired a solid axle from what i think was an early 80's land cruiser. I was wondering if any one has used one of these. Also since it was originally a sprung under configured axle will i need to rotate the knuckles to acheave the right caster angle. Any help would be appreciated thanks.
