wideawake,
Hahahaha, yea that picture looks familiar enough, mine was like that before the change. Ok, here's what you would need for your front suspension...,
1) Replace the knuckles on your Laurel with ones that are from an A31.
2) The A31's absorbers will not be suitable as the spring retainers are off-
centered, suggest that you source for after-market coil-over type
absorbers.
3) The A31 knuckles comes with 4-lug wheel spindle (PCD 114.3), if you want
5-lugs then try getting the spindle out of a 5-lug Skyline and see if they
will fit, I am not sure about this but this is a possibility. The Skyline knuckle
assembly will not fit into your Laurel because your car do not have the
upper suspension arms.
4) Given that you already have the A31 knuckle installed in your car, go get
a set of 4-pot brake calipers and rotor discs out of a Skyline R32 or R33, these
are a direct fit. The non-turbo Skylines have 4-lugs while the turbo ones
comes with 5-lugs, mine was from a turbo but had them re-drilled for 4-lugs.
Price difference between an R32 and an R33 4-pot brake calipers complete with
rotor discs isn't that much but get the R33 ones as the rotor disc diameter is
slightly larger and they are better.
5) The steering rack on your Laurel is probably getting "over-used" by now
because of it's age, if indeed you need to replace it go get the R33 GTS-T
steering rack. It will fit with some minor mods done to it. DO NOT use the
ones with Hicas that usually comes with A31 and R32 because your Laurel
is not 4-wheel steer.
6) Lastly, you would need to look for rims that would allow it to clear the 4-pot
brake calipers. Alternately you could use wheel spacers to rid the hinderance.
7) Oh..., I did mentioned to you before to use Toyota's Land Cruiser brake
booster and master pump simply because this will fit the 4-hole bolt pattern
thru' the firewall. I also told you the "trick", still got it?.
Hope the aboves helps.., good luck !!!.
