Is this a factory 70 PS gear?

[JimmyFloyd]

Just wondering if this is the stock Steering gear box for my 70, or if it was replaced before. Also, with the lines crimped like that, should I do anything to try and clean it out, or can I replace the lines and use it as is?

Numbers on it are as follows:

062 0 on the plate
5_86555 near the bottom nuts

symbol that looks like OO and then a 2 above the center nut.
