Learned gentlemen,

When I took the backing plates off the rear axle of my '62 BT7 race car the
four bolts each side had Nyloc nuts, with lock washers underneath.

With the lock washer in place the top of the thread did not connect with the
nylon - but it did with the washer removed.

The parts book shows just the bolts and nuts.  It does not show any washers.

As the car was built in Hayward, CA, in the mid-seventies as a track car,
there is much about it which is not standard.

My questions are:  

1.	Are the Nyloc nuts correct and, if not, what should be there?
2.	Is it correct to have no washers under the nuts?  I would have
though it correct to have at least a thin flat washer, even though the parts
book appears to show none.
