Highest MSRP for a 72 K20

[72 tigger]

Had some time and added up a K20 loaded with every possible factory option. Came up with a MSRP of $6,385- doesn't include dealer installed options such as: shoulder belts, tape player, etc. Does anyone have a list/price sheet for dealer options in 72? Would be interesting to see how expensive a 72 truck could be. A possible example of a "loaded K20 window sticker" http://67-72chevytrucks.com/vboard/s...d.php?t=685569 (tires are confusing on this truck- all the other prices look correct). Thanks for any input!
