I should have said I have a '54 rearend that I changed from a 3.90 to the 3.55 from Patricks. I've searched al over the web and junkyards/swap meets within a 50 mile radius of my address- nothing. I tried to rehab the original gears today. I cleaned up the scars in the teeth with a Dremel and straightened the shaft on the driven gear to the point that it spins freely. Got everything put back together tonight. Will try it out tomorrow.
