Hey guys, can anyone tell me if there is any value in an original shop manual and an owners manual for a 70 240Z?

I also found a workshop manual (book) from Autobooks and authored by Kenneth Ball for the 70 thru 73 240Z's. This is a 30 year old edition. Is it worth keeping?

Thanks for any info.

There is value in these items. Many people with these cars do not have these books...like me for instance.

If you decide to sell them please let me know.
