If you want to keep it 100% stock, you have to replace short/long tie rods and entire drag link.
If not, on my 70 EB, I converted to 78/79 steering box and used these Chevy parts to allow both tie rods
and drag link to be adjustable (parts are beefier than stock 78/79, 1/2 ton stuff also). Uses internally
threaded DOM tubing between both tie rods and drag link ends. Can buy it as a whole kit,
even for 78/79's. I did have to ream tapered holes in knuckles, but they are from a 77 bronc, so not sure
if you have to do anything on 78+
Also, if you look on floor in first pic, you can see I cut upper end of stock drag link, and welded on a short tie rod end with adjuster.
Very handy to get steering wheel back in line, if you've done susp or body lifts (since drag link is normally not adjustable).
