Mopar Direct Connection Performance Catalogue's

I would like to add to my collection some Direct Connection Parts Catalogues, the years I'm after are 1972 to 1976.

I think the part numbers started with SPT then a number, I have tried EBay & a few other web sites with no luck.

Can anyone point me in the right direction to get these?

Please note that I'm in Austraila & will need to find someone that is willing to post by USPS to me at my cost.

Cheers
