RO23Dave,
Jim and I speak almost daily, to the best of my knowledge he is no longer selling any of his parts to the general public however he will sometimes help out his friends if he has parts to spare not destined for his own projects. His number is 727-432-4364, but PLEASE keep in mind, he's not actively selling parts and is usually short on time, please be respectful in those regards,
BTW, while it's often possible to interchange parts between 66 & 67 B-body cars, nearly all componants are somehow unique to each year and wouldn't be 100% correct if swapped. If you have a 67 you'll likely need 67 parts, many Belvedere I & Belvedere II parts will correctly interchange with the exception of roof trim, deck lid trim, and some other minor misc. items. 4 door front clips from the windshields forward are all identical within any trim level cars as compared to 2 doors.
