Great picture Dan...the part in question is on the far left of the photo...the one with several orange tubes connected to the plastic piece colored in white and black. The black and white pieces are held together with a "pin" with "barbs" that pushes thru a hole in the center of both pieces and locks the two pieces together. One end of the pin looks like the round white thing in the center of the big orange piece. It can't be seen in the photo. Just not sure what to call the piece.

Anyway, I found a 3/8" long bolt with nut and two washers and got it back together and working so far. Not sure how long that will last. I'll be looking at the web site of the fastener place.

I did find a complete used unit for $75, but thought that was too much when all that's needed is a 50 cents part.

Thanks for your reply.

James
