Just wanted to post an update for future searchers... I was lucky enough to find the shuttle car at the back of the boom, inside, just lying there... We were able to use a fish tape to run the lines thru, the only tricky part was getting the fish tape around the correct pulley at the front of the boom. Took a few tries, but we got it. First we fished the forward reef line thru to the back of the boom, and attached the shuttle car, then fished it back to the front over the correct pulley. Then threaded the aft reef line thru the shuttle, and pulled it back into the boom with the forward reef line. All together it was probably close to two hours of fiddling, we work slow..... I guess that the former owner somehow broke the first reef line and it pulled out, and didn't know how to get new line back in.
One more project off the list.
