Purchased a Bendix PS control valve from seller on eBay with 5/16" pressure port, with a date code on cap 2K 25 A. Is this valve off a 1972 model year car? Also keep seeing a 6-19-67 date Ford made a change from 1/4" to 5/16" pressure hose on all Mustang cars. Is this correct and the Ford code for this change. Thanks
