I wonder if there is any quality control??????

Having seen a lot of heritage panels I can confidently answer this question. . . . NO!

I just did a front end on a customers race car and used an aftermarket front panel, found it fit better then the heritage one. The heritage LH fenders and inner fender suck, but all the RH stuff seems to be spot on, wish they could get there stuff together over there.

i think they must have a problem with there left hand wings.

mine was not the right shape , too tighter curve around the scuttle and bad fit to the front panel, when clamped down ,it rolled the wing and made the bonnet gap HUGH.

i managed to find a NOS wing in the end.

in the body shop, there is another mk1 in there, they had the same problem, they ended up un stitching the wing around the headlight, re shaping in places, they got to fit right, and spot welled it back together, a lot of work for a wing that should be a good fit.

I have done quite a lot of cars and I will stick up for heritage here. Yes they do have issues but I would still use heritage before any other.
The only problems I have found with the wing fit is trying to fit them to a copy front panel. The folded seam on the front of the wing quite often requires fettled but thats not hard.

There's a left and right, they didn't require any extra work to make them fit or any filler to finish the job. Whats wrong with them ?

I had a Heritage passenger wing for my pick up.

It was a good 1/2" too short at the A-panel end and no amount of pushing or pulling would make it fit.

I gave up in the end and managed to buy an old stock pattern wing off eBay, which fitted perfectly.

The drivers side Heritage wings do seem (or did seem) much better than any of the pattern ones.

NOS is of course best but remember that many of those that went into panel spares stock were ones that did not fit on the production line (or so I am led to believe).

IAIN, I know the pain on the seam of the heritage fenders, on the pickup I had to split the LH completely apart as there was over an 1/8 inch gap in the panel. Also I see in your pictures you have the late model fenders and they seem better then the mk1/2.

I had my shell on Ian Slarks jig recently and now knowing just how much tolerance there is between factory built cars its no wonder replacement panels fit some cars better than others.
Ian told me he see's totally unrestored mini's that have never been in any accidents and they can vary as much as half an inch either way (in length) from the bulkhead cross member to heel board. My own car although rebuilt, was all ok with the rear subframe mounting, heel board and toe board but it was a bit short between toe board and tower mounts, apparently this is very normal. It must be near impossible to produce panels that fit every mini perfectly when they can differ in dimensions from the factory :?:
I know minis were built on jigs but if you watch the videos of the factory assembly line they aren't exactly hanging around are they. I'd go as far to say it looks like they are running at the car with the panels and the next guy is running around with the spot welder. Also thinking about the sub assembles being the floor assembly and the front end assembly its easy to see how the two might have become slightly miss aligned... on occasion :?:

On a similar vein I was reading in one of the mini books a comment from Roy Haynes about the production of the mini clubman.
"On the subject of incompetent design, the Clubman grill was designed as a one piece stamping, but the body engineer came to me and asked if I would agree to having two separate outboard elements, around the headlamps, as individual stampings, with a central grill section. I said 'Why would we want that?' and he replied 'Well, frankly the trouble is that we cannot control the overall width of the car, so we cant have one stamping'. He was telling me BMC couldn't control the width of the car down to one centimetre..."

I don't know what the situation was like in the UK an later years of production, however here in Australia, the last couple of years, the panel fit was getting very poor and it was clear, looking at the Minis made in the last 6 months of production, they all knew they were getting the arse, the panel fit and subsequent production fit out is just woeful!

Wonderful work on the pick up very skilled work and a spot welder to die for.

On the subject of BMC/BL Quality the clue is in the title...it was the fact that they used Quality Control that was the problem.... The customer or the production line was the quality control but only at the end of the processes, if it did not fit or work it was rejected..... too late.
However if they had applied Quality Assurance, where all the parts/cars were checked and assured BEFORE they were shipped the problem would have been very much reduced.

Get all the bits right in the beginning and quality assure the assembly then the finished product could have been so much better.

In my fathers 60's through to 90's Body shop they always had to refinish replacement body panels before fitting, as they were usually the rejects from the line, on all manufacturers.

It was common though he had a Renault 4 damaged in transit, which was 2" (5cm) longer on one side to the other direct from the dealers he tried to pull it on the Cellette jig but gave up thankfully, only to find they sold different lengths of chrome side finisher to accommodate the discrepancies !!
