Forward rake & wheel recommendations

[Spille85]

Hi everyone, I'm a proud recipient of my fathers 1967 3/4 ton truck. I know its not in the best of shape, but I'm hoping for some advice. I know the tires on the rear are much larger, but as long as I can always remember this truck has always had a rake to it. Is this truck suppose to have a rake and if so, what can I do to level it out. Finally, I'm having a tough time finding 8 lug wheels for this truck. Any recommendations on what brand wheels and tire size I should go with. My goal is to obtain a level stance with pretty much the stock tire size or maybe a little larger. Thank you

Your best bet is to put 4 even sized tires on it so you know how much higher the back is then if your back is trailing arms id suggest lowering blocks because the springs may be sagging
