Very Rare BOP Early Model (steel vent tube) Heavy Duty Thick BOP case with the extra Webbing and Thick support rails on bellhousing and Pan rails. This is a Brand New early model Service Replacement case. I have had this for over 15 years. This can be used for a PQ (69 Trans Am and Ram Air), PX (68-72 GTO), BB (Stage 1), Ow (Olds 442) and any other early BOP restoration project. It doesn't even have a tag plate on the side, But the numbers stamped on the other side indicate its a True GM service replacement case. I have never seen another one like it since I purchased this over 15 years ago. I don't think these can be found any more Brand New. Pics show you it is Brand New, Never used. 903-258-5003. Dan
