Well I went and bought the rear axle assembly for the B210 120Y, I paid $100.00 for the complete thing. The only little concern I have is that its the rear axle assembly for the B210 Wagon not the sedan. My question is will this one still work on my B210 120Y sedan, or will I have to do any modifications? Another thing, the place I bought the rear axle assembly also has from the B210 wagon the two front shocks complete with the coil springs, will these also work on my model?, because I really need front shocks - mines are dead.

I'm pretty sure the should still be the same, the only difference could be the ratio, and maybe the w/cyl size

The wagon rear might be slightly different, but I would think you could make it work fairly easily. With B110s (Datsun 1200), the sedan/wagon, coupe and truck rears are all slightly different.

The front McPherson Struts will fit your car. However, some B210s have smaller brakes than others, so look it over carefully.
