Can anyone tell if a steering gearbox is a ws6 just by looking at it. The only part number on it is stamped on an end cap and is exactly that, the part number for the end cap. There is a stamp sized plate that has been ground flat that has some numbers stamped on it but those don't match any gm #'s and there are 2 raised numbers on the gearbox housing. it does have the 4 bolts that are on the cover that hold the gearing inside the housing. Do plan on selling them on ebay soon as i can verify that they are ws6 gearboxes.
