Transmission Safety What Fits

Why not build your 727 so it doesn't have the grenading issue? Valve Body with LBA (Stock valve bodies have this feature) 16 Roller Ultimate Sprag. & a billet steel reverse/high clutch drum. Sure it's a few more $$$, but a lot less than a prosthetic leg & no hassle trying to find a blanket to fit that wont guarantee bits of the trans not coming thru the floor.
Food for thought??
