MG MGA - Speedometer cable replacement

Does anyone have a photo of where the speedo cable connects to the transmission?

My garage is packed tight right now so before I move everything to make room to jack up and get under the car I'd like to see if it's easy to get to or if I'd be better off calling in a favor with a friend with a lift.

Thanks!

Right side of the gearbox, just forward of the rear mount, tucked up inside the tunnel.

If you intend to do this on the floor, jack it up high enough to get well underneath on your back with two hands up inside the tunnel in the tight space.

It is a knurled nut similar to the one on the tachometer drive at rear of the three main bearing engine. If it is tight, or has dirt in the threads, you may not be able to turn it with your fingers. Channel -lock pliers come to mind.

Ken, I wish Beaufort wasn't so far away from Gowensville so you could join us for BBQ tomorrow. You're welcome to use my lift any time.

Thanks Barney - looks like I'll call in that favor and use my friend's lift to do this.

Jud - love the rocker - is that a Snap-On product? Just looked up Gowensville - looks like about 250 mi, so yep, too far for a quick trip. Will you be a Dillard 2022?

I plan to be at Dillard. Hope to see you there. I plan on driving the '72 MGB.

ps: maybe someone will want to swap a set of original wheels and new tires for my chrome wires - God! I hate wire wheels.

Using my friend's lift the cable replacement was a simple job. Only difficulty was the old cable was wedged pretty tight between the transmission and tunnel.

If was doing this from the floor on my back it would have been difficult, but having the room while standing up under it to leverage in a long screwdriver to lever it down and out was a breeze :~).

Combination of the new cable and NOS speedometer resulted in rock steady needle and, yet to be checked by GPS, an accurate mph reading.
