Does anyone know what size the elbow adapter is on the bottom of the power steering valve on a 1710 tractor? I had a leak from the compression fitting and took it off to fix it... and then lost the fitting.... I am wanting to replace it with a swagelok type fitting instead of a compression fitting. All I can find online is that it is part number SBA340670910 and not a size of the fitting. Item 9 on the parts diagram. Thanks.
