Ok, I take back some of what I said.
Its not a RangeRover chassis, (I only said "suspect it is" anyway),
I don't know what the state of play was 5 years ago, DVLA now clearly state that the chassis must be to the "Original manufactuers specification" and that means that Designas coilers are out, as they plainly are not. Its not even a certain that a 88" SIII replacement chassis is acceptable on a SII, as there are a number of differences, especially on the earlier ones (like this was, B plate is about 1964 IIRC)
So to be honest I would say now we are on dodgy ground replacing with a mashland or richards standard chassis, I wouldn't like to be DVLA's test case... (All mine are still on their originals, plus a big stack of welded in patches, either fitted or overdue for fitting... )
JSG, Please note this is very much NOT a personal attack, nor do I wish you any personal ill-will. I didn't even know it was your vehicle, as opposed to one you merely had a picture of.
Your vehicle may well be perfectly legit because of when it was built, but there are an awfull lot of people out now building vehicles like this, and claiming fraudilent registrations. I am concerned that this means a lot of misinformation is floating around,
e.g. a lot of people claim their RR hybids to be SII because of the bodypannels being SII, which its not counted by DVLA for anything.
I think it was more like 10 years ago now the rules changed, but wouldn't like to have to bet on it...
While I may be new to this particular forum, I do happen to have spend a certain amount of time working on landrovers,
and while I don't claim to know much about some aspects of Series truck... (only thing I know about gearboxes for example, is where they fit in the chassis, and which levers to move when...) I think I am reasonably well up on registration issues, having read a little about them, including all I can find that DVLA have to say on the matter, and having got involved with some complex registration issues relating to some of my own vehicles. (E.g. I am currently working on getting back the registration of my 88" SII, which happens to be the oldest surving SII anyone knows about, being built on what I belive to have been about the third day of production.)
