You might check this thread (

I threw this idea around about 4 yrs ago but never got that far since I busted the frame on my 82. A lift spindle is the best way to lift a 2wd without going full custom. As far as I am aware nobody currently produces lift spindles for 73-87. AIM did but I have never heard anything good about them.
