Larry, thank you so much for your insight and help. I hate to ask any more questions, but I am unable to really read the numbers on the diagram. When I measure my car from corner to corner, using the drain hole just forward of the rear tires to the control arm brackets on the front frame rails, I get the exact same measurement when measuring the distance front to back on same side, for example front to back passenger side and then front ot back drivers side. When I measure criss cross there is a 1/2 inch difference. can you tell me what the values should be for these measurements and or is there somewhere I can find the diagram so I can enlarge it enough so as I can read the numbers? Again thank you so very much.....
