How You Can Get an Index
Indexes are published periodically.
Most of the PSP’s which could
potentially apply to the most recent
Oldsmobile models will be listed in the
most recent publication for that model
year. This means you may want to wait
until the end of the model year before
ordering an index, if you are interested
in buying PSP’s pertaining to a current
model year car or truck.
Some PSP’s pertaining to a particular
model year vehicle may be published in
later years, and these would be listed in
the later year’s index. When you order
an index for a model year that is not
over yet, we’ll send you the most
recently published issue. Check the
ordering form for indexes for earlier
model years. Cut
out the ordering form, fill it out,
and mail it in. We
will then see to it that
an index is mailed to you. There is no
charge for indexes for the 1989-1993
model years.
Toll-Free Telephone Number
If you want an additional ordering form
for
an index or a subscription, just call
toll-free and we’ll be happy to send you
one. Automated recording equipment
will take your name and mailing
