Denny,

I had some issues with the rest on my 82nd airborne and I bought it for the same reasons as you did, a WB that kept acting up...
The rest itself was perfect, I just had bought an older model with a straight mounting arm. QAD gave me good info and sent me a new one for nearly nothing. They made the mistake of sending me a RH for my LH model and they corrected that by sending me a LH arm for free.....so QAD are good honest people to deal with.

I just looked at the instructions and followed them and I had no trouble installing.
To avoid the out of sync problem I drew the bow back to get the normal launcher in a 90 degrees position without screwing the clamp tight.And then Ijust moved the clamp up 1/3 inch, checked if the launcher stayed up 90 degrees and did that again, just to have as less of strain or pullon the cables as possible to get the launcher up.
Works fine now....

About your WB, you should try and set it with a lasertuner such as the Easy eye or the laserplane.....that fixed it without all the tuning.....
