You are on the track with your plan, here is something I learned bringing the 70 back on the road. You can mess with the carbs and clean them and what not, but buying new jets, needles and carburetor boots really got the bike rolling. My jets seemed cleaned and OK, but first time I put new ones in, she started right up and run and idled nicely even before synchro.
Also, not sure where you stand, but I replaced coils and cables and points with aftermarket and electronic ignition. It was easy choice, since the cables were shot dead - but getting rid of points is IMHO the way to go.
BTW I have similar background - my daily driver is 86CJ7 - done frame up on it 2 years back; the nice thing on motorcycles is that everything is decent much smaller than off road trucks.
Good luck with it and post pictures, that's what this forum wants:)
