Hey Richard,
I have a new 100 tank from AHSpares still in the box but a few years old.  Never used it.
Shipping might be a bit spendy but I would throw in a used gas  cap.
I would also want $200 for the tank.

  re: "I wonder if the speedo cable’s routing was so far out of line that it needed a slight short cut to achieve its destination. My cable goes through a grommet to the left of the bottom left corner of the control box. Is that correct? Or should it take a more central route?"

 Disclaimer: I've not owned nor worked on a RHD car.

 Since the speedometer gearing is on the left/port side of the O/D housing--unless RHD cars are different--on a LHD car the cable has to make, in effect, a 'hard' 90deg left turn. Yet, besides the occasional glitch speedos in LHD cars work, well, OK (what matters is that routing isn't so drastic as to kink or bind the cable). I can't see any purpose for the optional hole as the speedo cable would make a more graceful, easier turn to the right in a RHD car. My LHD BN2 has its cable just wedged between the gearbox cover and the scuttle, unless I installed it wrong.

 I can't imagine why any speedo cable would need to go through the scuttle/firewall, if that's what you mean by 'control box' (aka voltage regulator). Mechanical tach cables have to, though.

Looking back through my files, I have contradictory info on this. So, here goes…..

My car is a RHD MkII BT7 with a centre shift box. It thus has the fibre glass tunnel cover which, I gather, continued to the bitter end in ’67.

You may recall that I sent in a pic of my tunnel cover a few weeks back and asked if it was an original or a latterly made repro. Thankfully, you said that it was original but it was pointed out that it had an extra hole. See attached. As I interpreted it, the “extra hole” is to the right and the correct way in is through the centrally located “correct routing for speedo cable”.

Assuming that is correct, I am led to wonder for what purpose some PO had drilled that extra hole……I wonder if the speedo cable’s routing was so far out of line that it needed a slight short cut to achieve its destination. My cable goes through a grommet to the left of the bottom left corner of the control box. Is that correct? Or should it take a more central route?

Thanks,

Simon,

I have a fiberglass trans cover that is yet to be installed that came from another LHD Healey. The hole that is open on yours has a rubber plug on mine and your pluged hole is open. It would make sense the speedo cable routing for RHD drive cars uses the hole normally pluged for LHD cars.

I have just taken a photo of my restored RHD BJ7 with speedo cable but not gearbox tunnel installed.  The speedo cable falls naturally in a position to pass through the right hand hole in the gearbox tunnel.  My cable did when I bought the (1963) car in 1977, so this was probably the original fitment for this car.

It would make sense for the cable to pass through the central hole in a LHD car.
