We have one also. It's a 1979 810 2 Door Coupe. It's in excellent condition. We had a mishap with the bumper today and are in need to repair (hopefully, not replace).
We have one and parts are difficult to find. The rear axle needs to be replaced for our 79 Datsun 810. We've been seaerching all over and haven't been able to find the parts for this. If you know, please let us know. Thanks.. vjones352004@yahoo.com
