Problem Solvers
This is like using a claw but more expensive. Its advantage is that it will not interfere with the axle position in the dropout.
The OP's problem, of course, is that he doesn't have enough dropout left to bolt in the axle.
Even if the axle would hold in place with half a QR, it probably wouldn't withstand the forward torque from the chain.
