Hey ppl....... brand new to the forum and Datsun ownership and yep..... I gotta stupid question or two.
Have bought a 1980 Sunny for fun. Dunno much about it and have only seen it at night. Paid $150 for it, so it ain't in concourse condition.

Goin' to pick it up this weekend, so I can't even go outside and have a look at it.
Plan is to old-skool-cool the sucker. You know, venetian, whitewalls and serious slammage. Maybe a nanna style sunvisor and bang some nice chrome VIP style mirrors right near the front on top of the front guards.
Anyway, here's my stupid questions.
Firstly, it's a 1980 model. What do I do as far as putting fuel in this thing?

Should I be using high octane unleaded and an upper cylinder lubricant such as flash-lube?
Now, dumping it........ are we talkin' coils in the front and leafs in the back? That would be okay cos then I'll just slot some blocks in the back and compress the front coils. Has anyone used coil clamps to lower their car? I know about them, but never seen them used, so I dunno if they are any good/safe/effective?
Also, I tried to insure it for the drive home when I pick it up, but they wanted to know if it's a 1.2,1.3 or 1.5. I have no idea, but when I get to it is it really obvious what size motor it has or can someone give me some tips as how I can tell?
Okay, that'll do for now...... I'm sure I will have more questions once I actually pick the car up.
Thanks in advance for any help you guys can give me.
