Suspension rebuild first time

So I've been building up parts for years and I'm looking at taking the big step this next week.. I had a freind weld up a 1973 kmember and lower arms. Picked up remanufactured spindles and tubular upper arms plan on getting a borgenson and big brakes. But want to make the swap i the next week for fall fling out here in LA..
I was going to do it with a Jack and jack stands and trying to rent or borrow and engine hoist.. any last minute advice?
