Need your opinion. To rebuild or run as is?

Thanks for all your suggestions guys. Really glad most of you said it would be fine because I ended up needing a radiator. Ordered and received my axel parts a couple weeks ago, but have been too busy to start until today. Opened her up and break cleaned her out looked over the axel bearings and not pitted and no bluing. So slapped a new pair of axle seals and a new cover gasket. Removed and blew out the breather, thankfully that was suggested I probably would have missed that and I found something in it. Filled with new fluid and wire brushes it an put rust converter on. I have new wheel studs arriving in the morning so hopefully get those in and rebuild the brakes and put a coat of paint on then I'll be ready to try and fit her in. Also have to put the new radiator in so it will be drivable.
