Those Rhino transaxle cases are done very nicely; too bad they are for a different application and the top strengthening ribs don't do us any good. What is nice about those cases is there's no wear in any of the bearing seats (a chronic problem with high mileage used cases that have been rebuilt more than a couple of times- try to find one that holds the pinion bearing properly or an intermediate section where the shift rod selector holes don't need bushing!).
In our cars (as well as bugs) the force is down and transaxle cases break through the bottom, hence the reason guys with cars that can pick up the front wheels weld magnesium plate to the case bottom. Most Speedster owners don't have to worry because no matter how much power you have, if your car isn't set up specifically for drag racing you'll never develop enough traction to put that much stress on the case.
The cracked case was in a friend's high 11 second '65 bug (it would pick the front wheels up over a foot!) and was caught upon inspection (before disaster happened).
