[Healeys] FW: Bonnet hinge on BT7

Fri Apr 4 08:31:05 MDT 2025

 Thanks Steve,
I just wanted to correct you to say the hinges should be on the INSIDE to 
be able to read the number stamped on the bonnet.
Some funny incidence is seen on.my 3000 BT7 MK2. The number on the bonnet 
catch and the number on the bonnet differ in the last digit by one. I 
suspect at the assembly line they swapped them with the car after.

Well, I screwed that response up.  I mean to sat that the hinges are 
supposed to be on the INSIDE of the bonnet flange.

Sorry.

The hinges are intended to be on the OUTSIDE of the bonnet flange.  During 
body manufacture, Jensen Motors stamped a number on the driver’s side 
bonnet flange (in reference to LHD cars).    If the hinge is on the 
outside, it will cover this  number.

My understanding of the reason for the “Jensen number” is that the 
bonnet/bonnet latch and boot lid were hand-adjusted for best fit , and it 
was intended that these parts stay with the car they were fitted to during 
later disassembly/reassembly operations at BMC in Abingdon.  The numbers 
identify these fitted parts that belong to a particular car.  Originally, 
the same number was stamped in three places on each car:  on the fixed part 
of the bonnet latch, just in front of the radiator; on the driver’s side 
bonnet flange where the hinge is bolted; and on the underside of the boot 
lid where the prop rod attaches.

The number is a letter, followed by one, two, or three numerical digits.    
A letter could accommodate 999 bodies before changing to the next letter.   
 The first Phase 1 BJ8s had the letter E.  The last cars built had the 
letter V.  The very last one built had the number 2 and no letter (I don’t 
know why).

These numbers track the body number closer than they do the VIN (not 
surprising, since Jensen built the bodies and assigned the “Jensen 
number”).  They are a good indication of the actual sequence in which the 
bodies were built.

Anyone with a BJ8 who hasn’t already done so, please send the “Jensen 
number” on your to car to me.  So far, I have them for 424 cars.

Thanks!  If you really want to be helpful with this, please provide photos 
of your numbers.

Simon,

The parts book, while not definitive, suggests the arms/hinges go on the 
outside and the bolts face out. See attached.

 Its an adjustment, inside or outside or different on each side.  Make the
 gaps even. 

 Best regards,

     So, I had my bonnet resprayed – don’t ask – and drove the car the 100
     yds(!) to the spray shop whereupon we could not decide whether the
     arms/hinges go outside or inside the mating surfaces on the bonnet ie
     to which the hinges are bolted. Of course, I should have taken a photo
     but was in a last minute panic for other and better reasons! (MkII
     BT7).

     In the end, we went with hinges outside, bolts facing inwards. Seems
     to work but was not easy to get a nice gap all round.

     What’s the collected wisdom?

     Thanks,

     Simon
