In the instructions for the OK 511CR (hybrid credit form) it states to attach "A copy of a paid invoice itemizing the cost of the equipment and installation must be furnished; including, if applicable, the type of fuel to which the vehicle has been converted." Does that mean manufactured cars as well? I was going to include a copy of my title if it was actually required.

Still happy with everything for the most part, even though I'm not getting all of the Federal Hybrid credit (about $400 short) I am getting the $1500 OK hybrid credit that I had not planned on initially.
