stag mk11 HEA

[mickjo]

Just joined the club after buying a manual 1972 mk1 stag.I'm just trying to get some background/history and authenticity to my stag and I hope you can help.

The chassis number is not an original triumph stag chassis number, but one suppliedby the DVLA. The carhas no commision number or anything. ThusI assume the number plate will not be the original number only one given for its approximate build age. So what am I left with?The gearbox and the engine.Unfortunately my engineis stamped as a MK11 engine with a HEA stamp at the end. So that gives me no clues. Could the gearbox give clues tocommission number?I'm hopeing the gearbox is the original, andis the onlyremaining traceable mechanical itemon the chassis. Any ideas where to go from here.

Also as another point my engine is marked HEA whichis a High Efficiencyengine for an automatic gearbox. My Mk1 is amanual. Is there a physical difference between the MK11 HEA and HEengines?

If I recall correctly there's also a body number which is on a small painted plate in or around the engine bay (maybe on a front suspension tower??). This doesn't correspond directly to the chassis/commission no, but should be in the same sort of range just as the the original engine no would have been. I assume the way it worked was that the bodies were built and numbered sequentially, but not necessarily used in that order to make complete cars.

There is a 1/2" wide and about 5" long, pop riveted stamped plate next to the nearside bonnet hinge with the chassis number on it. And there is the samechassis number manually stamped (quite crude looks like I did it) on the top of the offside suspension strut. I'm pretty sure there are no other distinguishing marks that could identify the car. The car is very solid however requiring alot of body prep for paint. And assume sombody previously has completely stripped the car and its been left like that for a few years before it was rebuilt and has lost lts identity and been given one by the DVLA. The log book states it was rebuilt with spare parts. Its a shame as I would like to know a bit about its history, I feel its all part of driving and owning a 36year old car.

Don't think this is the chassis number, if it's an unpainted plate it's the body number and it may or may not match chassis number, though according to James Taylor's book they should be close. It was added after the shells had been spayed. There should be two, one painted one unpainted near the left hand bonnet hinge. The painted one is another number that no-one [1] seems to know what it's for.

What number's stampedon your plate?

[1] at lease no-one I've spoke to.

Don't think so apart from the obvious auto bits. Block/pistons/heads etc are all the same
