Bill do you have a FTI aluminum valve body? Seems valve it self is about .10 larger diameter. JW case also seems to be thicker around solenoid which means more material inside. Easy fix is die grinder,just not how I like stuff fitting. Going to ati,reid or similar case later but that 1300 I don't have at moment since buying trailer tops the need list. The one I borrowed last year for while has since been sold for more than I wanted to put into it.
Trying to find out wieght of reid or ati and compare to jw case and bell. Have to run 2 piece because of hemi/glide combo.
