I just checked it out today, I was wrong about the engine code, its an ED case (1.8L 1975 transporter) still a solid case for a buildup imo. The other one is a CU case (2.0L vanagon ) as it has the enclosed breather tower. Same price for either case. I will be in Oakville working on my ghia this weekend, it will probably be alot closer if we meet up there.
