Unfortunately, at least on my spare, it's a blind hole.

About an inch deep from either end. There can't be much plastic between the two holes, but if it were bottomless, would that allow the cable to penetrate too deeply? And it's probably blind to stop oil leaking out of the tail that way; **note the oil scroll**. Though that makes me wonder why there's a rear hole anyway. Oooer missus. ...

Yeah but no but, all you'll get is 90's music Guy. 🤣.

I used to use a tax disc aerial. It worked suprisingly well. I've probably still got it somewhere, but I stopped listening to the radio in the car yonks ago.

No good to you now though if you've bought something.

Here's a modern version. Expensive though.

Thanks all. Ive ordered the one like the link Jeremy posted, except with a 2 m, not 5 metre lead. As long as it picks up a signal to work a mid 1990's radio thats all that matters.

I fitted mine a long time ago and used a rubber stub type ariel up under the dash passengers side.

Seems to work Ok but Ten I don't use the radio much.

It was Bernie that questioned me. I was going to put error down to old age but Bernie is older than me!

FM is still broadcast; even my modern has DAB & FM and the FM sometimes has better reception.

Aaaargh! Who throws away perfectly good YA hen's teeth, Willy. Oh well.
After another trip to Cairns today, it turns out you were spot on with your comment on the 9th September (above), re. that inner ridge of the piston needing to be reduced (milled down) to allow the secondary seal to sit down better. I have an engineer mate lined up to do that; plus, Brake Man recommended we add extra holes...

Les, I did wonder as my speedo was reasonably accurate with the 22 pinion gear. Certainly within the 'waver range' of the dial needle.

My car has the 3.9 diff

How would I know if my radio is fm or digital? Did I imagine they stopped doing fm radio signals a while ago?

I mentioned earlier that I had a 24 tooth gear (white), that is correct. However my diff is 4.22 and not 3.9!
