Reid bells bolt to Reid and BTE cases. And with a reducer ring ATI t400.

They will not bolt directly to your JW case. JW bells bolt through pump bolts.

Reid and ATI have a seperate flange.

JW is no comparison to Reid or ATI. Reid has no internal sheild and the flange is heavier duty.

If your using a jw case this is all a wasted discussion
