Re the hand control could just make up a receipt on Word or something, fill in the form on Chrysler's website, and have the dealer sign off that hand controls are present in the vehicle and get your $$$, happens quite often. But if you have a receipt from a real vendor, just fill in the form available on Chrysler's website, have the dealer verify presence of hand controls, and get up to $1K rebate. Same process.
