does a 904 slant torque converter=904 sb torque converter?

I think I'll buy a new converter. both are 904s, the slant has a 20 some spline count while the sb trans has 30 some. also I need those shumacer mounts to mount to the slant k-member. it's a 67 dart and a LA 318. any way I can get by the $150. if I had dimentions, I'd be tempted to make the damn things.
