I got a set done last year for the Balloon Chaser F-100 I have, and I think that was one of the last I have heard of getting done. He had a mini-stroke while mine were at his place. It took me weeks to contact him and when I spoke to him, his speech was not well, which is why he said he had not been taking calls.
Jeff picked them up for me, but Mike had just set them out for him, so Jeff did not get to speak directly with him then. We have not been able to reach him since.
