To finish the story; The nut on "B" being a castleated (sp?) nut,secured by a split pin. This castle nut backing the said thackery washer,which for those who may not know is a double looped spring washer.
The above info previously supplied to me, by both the thread starter and Doug Lavoie
(the forward two anchors have plain nuts (7/8" BSF) and are not drilled for split pins)

Good info to have, so thank you for posting Michael R.

7/8" spring washer

This Thackeray spring washer, as called for on the track adjuster lower rear of three bolts ... does anyone have a source for these in 7/8" ?
As a double coil spring washer, a similar item is common in the hydro line installation business, where the washer can compensate for wood components
swelling or shrinking. A different finish for sure. Any hydro linemen have a few spare?
