Have a link to a thread with the part number for the brake cable? Plan on using a split case and post 8/80 40 series axle in my FJ45LP-B
I don't, sorry. I sent a used cable from a 2008 HJ79 to 2manycruisers back home in Santa Fe and he said it fit (not with a lot of spare cable, but fit). I will see if I can get the part number for it.
They are certainly available from the wreckers here. Remember that they fit the 79-84 style handbrake wherer the lever is on the transmission hump. It will not fit the pre-78 style where the lever is under the dash.
You can ring Rod at Just Wrecking Toyota and he will send one off to you right away. I think I paid au$150 for it here. Rod's number is +61 8 8359 4499.
Cheers,
Josh
