has there been any complaints or questions about the belts being really stiff out of the box??....i am building my car right now and i soaked the belts to make them flex more but when i assembled the diff assemblies into the bulkheads, the belts are very very tight. I know i have the direction of the bearing housing in the correct order and everything is lined up. One thing i did notice is that the bearing houseings, all 4 were the same and in the manual the fronts seem to be centered and the rears are off-set. Also, does the long belt go on the inner drive pulley and the short one on the outer?
