Well guys I goofed up again, I ordered a h150 carrier from a b210 for my dwarf car with the help from Doug on here and I received it today and it will fall into the housing. Now I have two carriers that I can't use and still don't have one to use. I measured the opening of the housing with a tape measure and it is 6-7/8 inch.do I have a h165? That's my next guess but hell I have been wrong twice! Lol any help is greatly appreciated. By the way this housing and axles were cut down for this car by someone else and there is no telling what the hell it is and the guy is dead so I can't call and ask.thanks again.
