man, that looks like it was running that way for a good bit. the crank bearings indicate poor maintenance intervals, but the cam bearings look pretty typical for magnum. those things seem to be made of gorgonzola and puff pastry.
you silence!
some of us don't adhere to the gregorian calendar and instead mark the passage of time in seasonal themes.
soon green bearing season will be here followed by "over heating! help!" season... but first we must endure the bleakness of oil bypass and hei upgrades!
okay. it looks like you got the wrong pitman.
there's only two sizes of manual steering sector: big 1.22 and small 1.11
A's, B's & E's got the small sector, C's and Vans got the big sector.
there is no changer over in 73 like the power steering. manual is its own jam.
so if you're running...
extended oil change intervals? hung a chunk of junk that dropped in to say hello from a nearby neighborhood? collapsed or weak lifter and it just beat it to death? hung a valve momentarily and jammed it?
the fickle spins the wheel of mechanical fate.
that's correct. they are ball and trunnion output. but! you can either change the output by swapping the main shaft and extension housing (i'm simplifying here) OR you can make a conversion joint with a slip yoke in the driveshaft (much like a 4wd truck).
a word of advice here: what ever...
oof. that sucks.
but better you caught it rather than just knocked it in and lit her off and totally wrecked the thing.
if you wanted to be super lo-rent you could always slam a used slug in there...
generally seals are the culprit. followed by bearings or some knuckle dragging neanderthal reefing on steering couplers or pitman arms and buggering up the splines.
rarely do the internal hard parts themselves go bad.
