My apologies to White's, Kellyco, etc., but if you get in a bind (as I did!) --the plastic bolt that holds the coil to the lower rod on my MXT broke today, and I didn't have a replacement, so I went to the hardware store and bought a package of plastic toilet seat hinge bolts and nuts. These were ACE #45438, and they fit my machine perfectly!--I just had to hacksaw off about 1/2" of length. I still plan on buying the "real things" from White's, but these sure came in handy in a pinch!--I think they would probably work on other models as well.
