Hey guys, name's Dylan, I got a 78 280z 2+2 for christmas, just thought I'd say hey! also, I've been trying to find out what rear diff is in my car? I'm having issues ha yes I know there are forums galore on this, but I wonder because it says that 280s with manuals had the r200 with like 3.54s or something like that... but nothing is said about the 2+2 and honestly, I think the gearing would be lower because at 75 I'm revving on the top side of 3500. sorry if this is a nuisance, but I am just curious.
