I was searching last night on ECS with part number 33111214144 and it turn up not found. So, I looked through their drivetrain section and saw only hex bolts. I am surprised the torx head is much stronger...I'll get that replacement if it turns out only one or two is really bad.

For small head bolts the torx head with proper size torx socket and proper flush even seating of socket on bolt seems less strip able than Allen head bolts. I have Allen head on my driveshafts. They are cheaper to replace and easier to find, though. They would work fine if you can get the right grade— probably 10.9 or 12.9.

Since those two toxr bolt will take an act of congress to remove, I decided to apply a government response by kicking the can down the road. The drive side wasn't leaking...only the passenger side that didn't present any problems removing. I had also hoped that remove the output flange would allow complete removal of the upper bolt of the lower rear control arm as I am replacing with adjustable ones. Here are pics of the two frozen torx bolt and my attempt at the upper bolt on the rear lower control arm.
