Hi Schulz,
I had the exact same problem as you with my printer. You can go with the modified Wade's, but a better choice is to go with Greg's Hinged Accessible Extruder. I ended up buying mine from Greg.
Since I was in the same boat as you, I feel your pain. I'll happily print one up for you for free over the weekend. It probably won't be as good quality as one printed by Greg, but I'll guarantee that it'll work.
Drop me a PM with your mailing address.
