average build time? im stressed out

[TX58]

what is the average build time to get one of these old trucks done? I've had mine for six weeks and its completly stripped down to the cab and rolling frame. Im staying mostly stock on this 58 so theres no modern mods. I see guys here taking 5,10,15 yrs to finish a truck. I want to drive mine now! This is my first restoration and i would like to know is there a sequence to putting it back together? I know rust repair,primer, and paint are first. Whats next? should i paint it partially put together? Or in parts? Ive also got the frame painted already. Engine and tranny are back from the shop. Plan on new wheel bearings and brakes. Interior and trim are last? Wiring is mystery to me, but i plan on tackling it myself. Im stressed out here, need guidence.
Thanks
