Every user who reimbursed a retailer for Illinois or municipal or county retailers' occupation tax or paid use tax on the amount of the Federal excise tax on manufacturers of motor vehicles when purchasing a motor vehicle in Illinois between August 16, 1971, and December 10, 1971, upon proving to the Department of Revenue (hereinafter called the Department) that such user has received a refund of such Federal excise tax, may, prior to July 1, 1976, file a claim directly with the Department to recover the amount of such use tax or reimbursement for retailers' occupation tax or municipal retailers' occupation tax or county retailers' occupation tax.
