GM options information on a c3
Also the model year Corvette Order Form from the dealership for customers to order options available on their Corvette model.
There aren't a lot of options available to the '70 to '72 models. Options for these models include: A31,J50,N40,C50,N37,C50 ('72 model only),UA6,U69 or U79,PO2, PT7, PU7, CO7/CO8 (convertible model only), G81 (optional axle ratios-economy/performance),custom interior.
Also a no cost option choice of manual transmissions either M20 or M21
A total of 53 LT-1 ZR1 option packages included VO1, J56, F41, M22 as mandatory options. That's pretty much it.

Click on the link, scroll down to "Corvette" and click on "show", select/click the desired year, accept the usage agreement, and a pdf with vehicle information downloads. Examine the pdf, it is a copy of dealer ordering information, RPO codes (regular production options) manufacturer's data submissions, advertising, etc for the year in question. Years vary as to quantity of material. This is a pdf of the old vehicle information package available from GM. You can still get a paper copy but it costs for reproduction - pdf is free.
You can read about them here:

Good pics of them here:

Google LT-1 and you'll probably kick up several links.
