Well, no winners, but Bill and Larry were the closest.

Both the pin/clevis and the holes in the stirrup wear. It may not look like
much, but it doesn't take much to do the trick. Replace the pin - US
hardware stores have generic ones called clevis pins. On the holes, either
replace the stirrup, weld up the holes and re-drill, or weld washers beside
the >holes.

The broken piece was actually one side of the stirrup itself. From the
looks of it it had been broken for a while, and the cotter pin holding the
clevis to the broken part finally gave up.

No doubt, as the cover was held on with what looked like a mix of mucus and
chewing gum, no screws or seals to be seen.

Yeah, especially when instead of the pin there is a flathead machine screw
with a hole bored in the end of it for the cotter pin. The screw had a
profile like one of those silouettes of a vase/two faces kissing.
Gee, maybe X years of wear of the screw threads in the now oval holes had
something to do with the part failing? DPPO.
Anyway, I have rigged the pin back to the remaining side of the stirrup, so
at least I can drive.
The parts for a correct fix are on order. Isn't that easier than trying to
improvise?
Thanks for all the help
(esp to those of you who had me ready to rip apart the whole hydraulic
system before looking for a simple mechanical failure ;-)
