I have the "Assembly Manual" for a '54 Chev, and this is a '55 GMC, but I've
never found one for the GMC, so mostly I relay on the '54 book.

Does your book cover '55 1st GMC specifically?

I have cleaned and greased the pivot, and that didn't seem to make any
difference.  The new master is closer to the center of the truck, and I do
think its changed things a bit.  I had not thought about the body mount, and
the possibility that it has sagged.  I'll look at that tomorrow.

Thanks!
