I don't understand what you are trying to say about the 10 inch kick and 4 inch underslung causing the pinion to be above the trans output shaft----the pinion will be located from the ground and diameter of your wheels--it has nothing to do with frame kick or how its mounted--the ford 8 and 9 inch rears have probably the lowest pinion of about any rear except for a quick change lower shaft. Your problem is from the engine trans mounting angle and thats what you need to correct---especially with a short drive shaft
