Post by steady on Wed Sep 02, 2015 8:27 am

a 1st Gen, 1964-66, uses 2" wide springs,,,,,which means the U bolt holes in the axle are 2" apart,,,,,the 2nd Gens, 1967-70, have the weirdest springs in the world,,,,,3" at the perches, 2 1/2" at the U bolts,,,,,,,,drag links are 180 degrees out,,,,,that makes the steering knuckle different,,,,,,,so it is possible to use a 1st Gen axle,,,,,,you need springs, wider bushings, and a drag link........IF,,,,the springs are the same length to fit,,,,,,1st Gens are 48" bolt hole center to center,,,,,,how long are 2nd Gens?

If you haven't gotten the king pins yet Orielys has them in brass or bronse(don't know which) I wish I kept the box they came in so I could give you a # but they are available.Make sure you specifie you want metal bushings.

I think you will have a hard time finding Bronze bushings,,,,,and there is a chance that they might have to be reamed out for the kingpin to fit,,,,,,,,now those nylon ones are easy to snap in,,,,,,,IF,,,,
that kingpin wants to come out,,,,,,,you could probably go out at lunchtime and do 1 side if you have everything ready,,,,,,,,

@ Donivan:
Ah, so the gap is .0002 ... Man that's tight.
Also, I say "Hah!" to easily removable kingpins. Mine took 15 Tons to budge and 6 Tons to push out. Obviously, they were never ever changed.


@ Steady/Doug:
Looked on O'Reilly, and lo and behold they do have brass bushing versions! Of course, that's for the 5 lug axle.

Rare Parts, #30418, ~$170 - Brass bushings

Or, go to RockAuto and search for " MOOG 8494N "
~$47 + S/H - plastic bushings


The 6 lug's only got plastic bushings... Which means I'll have to make my set.

On the moog part number "N" is nylon. "B" is bronze, if you can find a 8494B thats what you want.

Steady, I have a guy here who says he has a 67 axle for sale with tight king pins.
Tight means either good to go or seized, I don't know? the other question is the camber

send me an email m1dadio@shaw.ca
