This is really interesting.....? I can't view your attached pics, would really like to see them.? Do you know of any other way to insert them in a message?? I've attached a pic of my RA Worm block which shows the 9/16" bolts and nuts on the bottom of the RA mounting and the Allen head screws on the top.? I screw in the 9/16" bolts into the RA Worm Block until the hole is visible through the Allen Head screw holes and then loosely attach the nuts to hold them in place.? Then I insert the Allen Head screws through the 9/16" bolt holes loosely, then follow Scott's video from that point forward.?
I just spent most of the summer rebuilding my G11T and took pictures but did not take pictures of the RA worm housing with the bold holes lined up (Uurrgghh!). To do that now I'd have to remove the nut on one bolt and remove the corresponding Allen head bolt, then snap a pic. Easy to do, but it would destroy my RA Worm alignment which I really do not want to do again.
Sounds like there could be different variations of the RA worm block assembly (not the block itself but the mounting hardware).? I purchased my G11T in 2017.
