Vintage Catalogs and Magazines

I am building a Jeep vehicle for vintage rallies. I would like to obtain information (only) from catalogs such as 1968-69 4Wheel Parts, 4WD Hardare, Cepek and magazine (I thingk Four Wheeler was the only mag at the time).

Its not the old mags and catalogs that I need, but the printed information on aftermarket parts, accessories and processes (such as spring overs, over drice, performance parts, etc.) is what I need to comply with the rally rules.

Photo copies, faxes, etc would work. I am looking for the information, rather than EITHER the 'collector status' of the catalog OR parts that are CURRENTLY available for a 1969 FSJ. I need to know what parts were available for an FSJ in 1969.

Hoping you can help with this info.

Thanks in advance,
Scott
