All the 4 cylnder "L" motor stock radiators I have had have the1 3/8" inlet and outlets This covers the 521s, 620s, and the 1980 720s.

I will be upgrading headlights, radio and fuse box. Could i use the 280zx alternator? I remember on 240z it's plug and play just need a jumper. Is this true for the 521 as well?
