"Just searching car-part and there is no listing for CV or Constant Velocity joint. What would this part be a member of? Front Drive Shaft? Front Axle Assembly? Front Axle Shaft?"

I can't remember what I searched on when I found it. I think the best vernicular would be 'half shaft' or 'front axle'.

"part interchange with other trucks do our CVs have?"

Rumor has it that 97 Trooper might work but I would think that the Amigo would be the better bet. No one has taken the plunge to find out for sure (i.e., actually bought one to compare).

"Merlin has to offer"

I didn't check - let us know. I paid $300 for the set I got from the bone yard (& felt lucky to find them at all).
