What Mel said! To add, I recommend that, no matter how many items of information the data plate has room for, ONLY put the builder name (Make), Model, and serial number on the plate. DO NOT put dates, gross weights, builder address, etc. None of that is required so why put it on there.
And to reiterate and reinforce what Mel said, make sure the data on the plate matches the info on the registration certificate EXACTLY. No room for interpretation on that one. If it doesn't look exactly like what is shown in the registration certificate, that's a show stopper.
Forewarned is forearmed!
