No sooner than we completed our restoration and made one good 400 mile cruise than the speedo quit working. Little did I know that the whole interior and tunnel cover has to come out in order to replace the cable. So today, I began the work.

I believe that, on cars originally equipped with OD, there was a metal access panel that allows access without removing the tunnel. You might consider adding something while you're at it.

or you may consider doing away with the angle drive and buy a longer speedo cable. Angles drives are inherently iffy and will break again. It will be a tight fit but it's possible. While you're at it you may want to replace the bracket exhaust pipe to GB for a thicker one as this one will break too.

Actually, I am installing one of the “split” tunnels. Either way, the seats have to be removed and the carpet pulled back but hopefully, the dash support can stay in place.

I like the idea of doing away with the angle adapter but, as you can see from the photo, it is a really tight fit where the adapter is. I am going to take a closer look to see if I can make it work. What is the “bracket to exhaust pipe GB”? Thanks for your suggestions.

Hello
Many moons ago, my OD speedo cable failed all I had was a non OD speedo cable which is shorter. Being cheap I put the shorter cable in, inside the car under the
carpet.Worked fine for many years. Oh, no angle adapter, never had one.

the bracket exhaust pipe-to-GB (to OD for that matter, the one just under the angle drive)

Anyone care to comment on the "split" transmission tunnels I have seen offered on Ebay...? I am about to pull my one-piece tunnel and would like to replace it with the new design two-piece if they are worthy...Ryals

I bought one for my TR4A and so far it looks good. I haven't installed it yet but will be shortly. Then I will be able to discuss fit and function. There are a few items that must be accessed from above and that means pulling the carpet back at best. Will let you know shortly.

This is the one I bought. In looking at the photos, I am now worried about whether the dash support has to be removed in order to pull the back section. I also hadn't seen the comment about the switching the side cover from the old tunnel cover.

I think the split tunnel is a great idea.
Either buy the above or modify your existing tunnel into a 2 piece.

Yeah...I'm thinking I'm going to modify mine into a two piece "just in case". I'll just use sound deadening to keep it together and if I ever need to get in I can just the deadening which is no biggie. That two piece is a good idea.
