According to Wayne up in Canada, the 70 series tie rod is perfect for a 40/55 housing w/ 60 knuckles:

Now I found some info in a thread over in the 55 section that included info about using 70 series rods when you put 60 knuckles on a 40/55 axle housing.

sadly, the earlier 40/55 uses smaller ties than the later version.
you could swap a later 40 series front diff in (1981 and newer) and then the arms off the 70 series and you will have a bolt up cross link.
if you do that then you can add 60 series PS and you will now have the drag link from the 70 series that is the proper length and HD upper arms.
you can get brand new cross and drag links C?W ties from Toyota, this is what i did on the 42 for PS upgrade.
this way the only mods to the steering is the connecting from the steering box to the steering wheel.
just a suggestion.

part numbers:
45460A ROD ASSY, TIE
45460-69125 1 $412.69
45450 ROD ASSY, STEERING RELAY
45450-69075 1 $371.69

i didn't pay near that much for these ones ... sure is nice working with brand new parts that actually fit the first time.

has the ends included and will work from arm to arm.
the other part number i posted comes with the ends but is too long ... i think ... for your application. it is for the 60 PS box, now, IF you can give me a measurement of the existing arm to crosslink hole then i can go measure what i have in the garage ...
in the pic you can also see the difference in strength between the 70 series arms and the 40/55 series ...
this is a 42 series axle.
hopes this helps.

so unless you go with 60 PS box, this relay rod won't work in your application.
hope this helps
