A few questions 1) What is the real difference between the Can Back, and the Pacyderm. Is it just the fram stregth, it says one can hold 350 ponds, and one can hold 200 punds. 2) Is it 150 dollars extra for the side windows? The order thing on the web sit is unlcear. 3)How much was shipping and handleing for you? 4) Which version of the top did you buy, and what was your final cost?\ Any help is appreciated, much to my dismay, the can back soft tops are still available for the 79 to 91 blazers.
