It’s mid engine. There is nothing added to the bottom. It is a pro suby trans. I have not contacted Rancho yet because it’s Sunday for one and two I didn’t know if that’s just how its supposed to look.

I know that in rear-engine configuration drag racers will gusset the trans case on the bottom to keep it from breaking during launch, but I'm of the understanding that it's only necessary when there's enough power, suspension and rubber to pick the front wheels off the ground.  Usually only the clutch throw-out arm side is done as that's where a crack will first appear.  This was in a friend's high 11/low 12 second '65 bug and was discovered upon teardown, before it let go completely.  I don't know who did the welding in the 2nd pic- it was stolen off this great big interweb thingie-                                                                                               transaxle case cracked        trans case gussetedAlan's car launching at Mission Raceway-                                                                                Alan's car launching

All the forces are driven out the bottom, so the heavier Rhino case (which has thicker webbing on the top and was originally used in a different configuration) isn't normally a benefit here.  As for mid-engine, I don't know, but I will ask a friend who I'm sure will.

Is there a matching gusset on the other side?
