66 Lemans conv. 489 BBC with iron heads. I have stock 66 GTO springs with 1" spacers, and Heidi's 2" dropped spindles Stock lower control arms and after market upper control arms. Tires are 245/75R17. The headers are about 2" off the ground. The top of the tire hits the underside of the inner fender well. Since Eaton made the original springs I called them to find out the weight rating and compression heights of a stock 66 GTO and a 66 Chevelle 396 SS with A/C. The guy I talked to said they had no information on either. How can a spring maker NOT KNOW the weight rating of a spring. They make custom applications so it makes no sense! Does anyone know there values. Any idea how to raise the car up 1" or 1 1/2 in.
