if you have the brg. out you can take it to a old school parts house. if they have anyone worth anything they can mic it and look in their brg. book and find a brg. atleast we used to be able to do it. i dont know of many ol timers left in the parts bus.i got a guy i used to work with that is aces when it comes to brg. hes found some i didnt even try to find.and i was good but hes better. im out of the parts bus. now but i still use him to find crap i cant.if no one will help you send me the measurements and give them to him. maybe he can come up with a part number.
