For those that used the GM Sag 800 box on your 48-50, what tie rod ends and drag link did you go with? I was looking at getting a kit from Classic Haulers, but they said they are discontinued because the guy that used to make the kit for them retired.

 

Why not use the Toyota box instead? Easier install, works like it was made for it (GM box results in a large turning radius) conversion parts available from Mid Fifty (the 53-56 kit parts just require a few minor mods to work on the F1 see Toyota Steering Box Swap For 1948-1960 Trucks .: Articles ), boxes are near bulletproof and available used for ~100.00 (try Car-Part.com--Used Auto Parts Market).
