Ok folks. Long story short I need a measurement from a sb mopar 727. What I May do is replace the bell of my IH 727 with a sb mopar ultra bell but I need to know that the depth of the two are the same from the pump to the mounting flange of the bell housing.....if a guy had a empty sbd 727 and measured from the bellhousing mounting flange to the gasket surface of the pump it should (hopefully) measure about 6 1/2" (picture attached). This is the distance I'm looking for if anyone has the means to help me out.:d
