Putting a 4900 together that had a Sharp Image chassis - question

I have a monitor that's on a 4900 frame, but a Sharp Image chassis was installed on it at some point in its life. The SI chassis was poorly screwed in there with 2 diff types of screws. I got it working, but the arcade monitor tube has noticeable burn and there's a weird spot (like burnt or missing pixels) on the screen and the color shifts weird. (pic below)

I also pulled a TV tube with the correct skinny neck and pinout.

I have a 4900 chassis I could fix, and I would assume that the tube and yoke were the original 4900 ones. So, I'd also assume the yoke readings would be correct for a 4900 chassis, but according to http://www.junknet.net/donor-tvs, it seems off.

4900 frame with Sharp Image chassis, yoke measures:
H - 2.8
V - 41.6

On junknet, states 4900 SHOULD have:
H - 2.6
V - 34.6

Close, but is that close enough to use that arcade monitor yoke if I do a tube swap?

I'd like to use the 4900 frame, a 4900 chassis, the yoke on the crap tube, and the donor tube.

Thanks for any advice. Pic of 'spot' on burnt tube below:
