Sounds like a decent plan. If mostly going to be a street truck, I would
add the rear swaybar and new bushings for the front swaybar also. My 79
has 35 BFG AT's, 2" lift and both sway bars. Mostly use it for towing,
but it really is a nice driver too, corners very flat.
Also, the 35 BFG AT is a very small 35 (compared to many other 35's),
maybe 34 actual dia when new (with the perfect rim width off the vehicle).
So small in fact that even with a plow on the front and only 2" springs,
it never rubs.
Here is another data point for looks/clearance, 2" lift,
no bod lift and 35 BFG AT (16.5 rims).
As far as mods and their sequence. I would do hydroboost brakes
after the new tires (assuming alignment is OK). The brakes on these
are marginal at best, even with stock tires.
