You are correct, the truck rear end gears DO NOT fit in the passenger car housing. There should be lots of 3:55 'powerglide' rear ends around Fresno. Contact some of the many VCCA or Inliners Int. Chapter folks down there. I just sold my last 54 (3:70 ratio) set, having changed all but one of my remaining cars over to open drive. Best of luck and stay out of the FOG if you can.
