Ok I've got a six inch lifted rear springs over the back axle and I am wondering how great of an angled shim can be installed on top of the spring perch. I heard that to much of an angle results in oil starvation inside the pumkin. So whats the word on this? I will be machining the angle into a one inch add aleaf from ORD. Steve at ORD was kind of unclear (or my interpretation of what he had to say was). So I thought I'd ask the question here and pick some brains. Thanks for your responses.
