I think you can buy the Hollanders manuals online,I've never been able to access any info from them without buying the book. And I wouldn't get enough use out of one to make it worth the $$ eek $$.
If there's an older wrecking yard in your area,cultivate a friendship with the owner or manager,and eventually he'll either look things up for you or let YOU get into the book and check things out.
