I've been lurking for some time - have had a love for Datsuns since a 510 infected me with the fever several years ago - but I finally took the plunge and bought a '74 620 yesterday.

The front end/brakes need some work before it's road worthy, but those wheels, grille shell, bubble sunroof and stink-bug stance made it too hard to resist.

I guess Ben (the guy I bought it from) raised the front end from where the PO had it, but I'm not sure if he just didn't re-align it afterward, if the king pins are wasted, or maybe a bit of both. Anyway, the front tires, though new, are already wasted on the inside edges, and it needs some brake work anyway. It's making me consider options for the swap to ball joints and disc brakes. I feel like if I'm going to do it, I ought to do it right once, and be done with it.

Well, I guess the good news is that I bought it right, so there's money left to do some things. Let me know if there sre some pitfalls that I should be careful to avoid.

Welcome to Ratsun Dave. Good to have you here.

 

Take some time and line one of the front wheels with the rear one behind it. Just sight down the front and back tire edges and keep trying until it lines up with the rear. Now go look at the other side. Likely the two edges are looking way outside the rear tire. If you can see that the front tire is turned in (toe in) then it's bad enough to need adjusting.

 

Adjustment is quite easy and just requires an adjustable wrench to loosen the two lock nuts and a pair of vice grips to turn the cross rod they are on.

I don't think toe is the issue as much as camber, but I can take care of all that soon enough,

I installed new lock cylinders in the doors today, for all the good that they do right now - no rear window until a new seal shows up. I'd just like to be able to secure it at night.

Park level and use a torpedo level on the edge of the rims. They look good to me.

Yeah, me too. I look forward to respecting Ben's vision, and tweaking it to my own. Pretty sure it will remain green in some form or another, and those rims and grille are definitely staying. Not sure about the bubble sunroof - he said it's a bit like sitting in a greenhouse in the summertime. I build/ride/show custom and vintage bikes, and this thing should come in handy for hauling duties.

My brother runs a brakes/alignment shop, so it'll go up on his lift this week, and we'll find out exactly what issues it has underneath. Then I get to weigh the options...

Welcome to Ratsun Dave. Good to have you here.

 

Take some time and line one of the front wheels with the rear one behind it. Just sight down the front and back tire edges and keep trying until it lines up with the rear. Now go look at the other side. Likely the two edges are looking way outside the rear tire. If you can see that the front tire is turned in (toe in) then it's bad enough to need adjusting.

Yes, welcome.

 

It appears that the truck may have wheel spacers on the rear axle (the tires are sticking out more than the front...?), so sighting the front to rear tires won't help with toe.

Just wider/staggered wheels, but yeah. I'll get it on a rack and align it this week.

Not too much to tell, but I did put a new back window seal into it on Sunday.
