Ah, well, yes. I should read more closely...

The front panels are interchangeable, mostly.
The main difference is the prescence or absence of the purple DPO button adjacent to the large knob.
A TDS754D has the DPO function so you will want a front panel that also has this function too. I believe it makes no real difference if it comes from a different model or revision.
My offer still stands though, let me know what you need exactly and I'll see what I have (if I don't have a complete panel, I might have the parts to repair yours)
