'70 AMX Rear Suspension Question

["Steven F. Brueggeman" <amcer@xxxxxxxxxxxxx>]

Was doing some detailing work underneath my '70 AMX and noticed the front
leaf spring bolts don't seem to go in all the way. There's about 1/8"
between the backside of the head of the bolt and the subframe. The bolt is
two different diameters. The thickest part is from the hex to about half the
length. The last half is smaller in diameter including the threaded area.
The thickest part will only pass through the inside of the subframe but not
the outside. Is this normal? I don't recall a washer being used under the
hex.

Thanks,
