Jim,
I meant no insult, only that Brian is an honest workman and had it in his shop, while we are looking at pictures. Sorry if you took it differently or I spoke clumsily. Yes, there has been some removed, that was clear, but the TG in RCA also obscures the step significantly in my opinion; also differences in photo scale, lighting and camera angles make it difficult to determine exact measurements. I thought the aim of the thread had slowly evolved to determining what was actually done, and was stating my observations based on what I can see, for use or refutation by others as they see fit. The only reason I spoke up in the first place is because I saw it differently from what most were seeing (at least one poster even seemed to imply that the step is now missing entirely), and it seemed like the right thing to do, although I had (perhaps now justified) misgivings in doing so.
Lucky,
Again, I am simply not seeing it the same way, and was stating another possibility, and I think the photos are not reliable enough to make a definitive measurement, but will defer to your experience. Perhaps my argument is "horse hockey"; if so, that makes yours the stronger.
