@isbcornbinder: I'm installing an entire AMC Pacer IFS clip with disc brakes on the '52.  So I'm not simply adding a rack to a straight axle.  In fact, the plan is to rebuild the entire front axle and suspension from the '52, and then swap lock, stock & barrel with the '51.  So I'm not "betting the farm" on home engineering.  On the '51, I'm ONLY converting the steering box to a '79-'85 Toyota pickup box…same basic mounting as the original Ross box, but it's "divorced" from the column by a joint that the IH doesn't have.  I'll have to have a machine shop make me a pitman arm compatible with the Toyota splines, but as long as I can mount and drive the pump, it won't be the piece of half-fast engineering you seem to think it's gonna be.[I saw a conversion on a Ford in which they bored out the center of the stock pitman arm and then cut the splined center of the Toyota pitman arm and welded them...but I'd prefer to have my pitman arm as one piece, for safety's sake.]

And I don't recommend trying to grind an L-R-S-series steering shaft down to a double-D; unlike later model trucks and other makes, the L-R-S shaft is HOLLOW, with relatively thin walls, and that's where the original horn wire runs.  I wouldn't even CONSIDER grinding that hollow shaft and weakening it further.

@ihcnut: In another post recently on the forum, someone determined that the single pulleys on the BG241 and the SV engines are the same part numbers.  It would then be logical that the double-sheave pulleys from the early '60's SV's would also fit the the SV.  So my thought is to use one groove to drive the alternator, as was done by the factory…and then use the second groove and a second belt to drive a power steering pump [once I figure out the mounting].

@granddadstruck: When I get mine out, I'd be more than willing to deal.
