Picked up this lightweight aluminum forward clutch drum for the trans -
I had this style part fail on mine. The splines that are expanded on the input hub started to pull thru the aluminum. The fix was pretty simple. The groove in the hub just above the expaned splines was machined slightly deeper to hold a flat snap ring. Then the the inside of the drum was relieved the thickness of the snap ring, aprox .060". Over 350 passes since. Make sure you put a steel front planet carier in it if you're using a trans brake. They will strip out the splines.
