When your doing something like a 500 Cad into an AD truck the original radiator position doesn't mean squat and, the front sheet metal clips will swap if you fab a new core support so they're the same truck from a swappers point. The dual roller chain from column to gearbox keeps the box in the rear steer position and eliminates snaking the steering shaft through the exhaust and other close areas. Not a problem with a small block but very crowded with a big hunk or iron like the caddy. The chain would wad the 3/4" steering shaft up like playdough and never feel the strain. Must be in perfect alignment and have an adjustment for tension. Trouble free for 200k+ miles. All the farm boys recognize the chain and sprocket setup cause the old balers, combines, thrashers(showing my age), etc., had them in many locations. Something different makes some leery but chains turn the cams in a Formula 1 engine 12 grand and twist cams in race engines that have 16 valves with 300# seat pressure each. As slow as a steering shaft is turned and probably 25#'s or so
twist to the power steering box I don't worry.
