Although a buyer was named more than two months ago for the Ford-owned ACH glass plant at Tulsa, Oklahoma, the company has yet to close the deal on the facility. "We are working on it as quickly as we can", said Della DiPietro, spokeswoman for Automotive Components Holdings. Ford bought the Tulsa plant and 21 others from Visteon Corp. in 2005. The facility, which makes architectural and automotive glass, was quickly put up for sale. ACH began offering buyouts to staff, which have been accepted by 160 Tulsa employees over the last two years. The plant now has about 500 full-time employees left, Ms. DiPietro said. She said it has yet to be determined whether buyouts will be offered to these remaining employees. ACH offered the latest buyout program in 2006, Ms. DiPietro said. She said the majority of those who signed up for the buyouts have already left the plant. "
