I'm trying to re-register my 3011, and have the registration but need the chassis and engine numbers. The plate on the bulkhead was painted over many years ago, and cleaning it off has not helped distinguish bits of it. I have loads of numbers, but cant make out what one fits with what, i.e which one is engine or chassis. I have 800/1200, 63727, 30074441 and even 1720, 5300 and 254. On the engine block itself I have HR 5963. Can anyone explain the differnet numbers? Thanks for any help at all!
