Just wondering if the strut tops from early models and later models are interchangeable? It's probably not okay to use different years for left and right of the car, but say you're using early model for front strut tops and later model for rears?

Strut tops?
If you mean top mounts (top hats) it shouldn't matter
The strut dimensions on all models are the same, even though early models had gland nuts and later models were sealed.
 
Although Toyodiy give a different p/n for early and late model strut tops (F+R), the only difference I have noticed is that with rear top hats the bolts are slightly longer on the later models, otherwise they look the same.

Coolios thanks Ian I can get a set that's cheapest if I combine the front pair from the early and rear pairs from the late, that's why I was asking.

"It's probably not okay to use different years for left and right of the car"
Shouldn't matter for the rears, but not ok for the fronts.
 
I just carefully measured some front strut tops that I think came from a '95 Bathurst, and I found they are slightly different to the '90 model ones on my car.
These would give more caster, because the top of the strut would lay back slightly.
So you wouldn't want to mix those up a have different ones each side.
 
 
 
 
 

BTW that may be one way to increase the front caster for the early models without going to aftermarket stuff.
My front caster rods are already maxed out giving about 4 degrees, and the front of the tyre is getting a bit close to the inner fender liner anyway.
 
I'm not sure how good the bearings are in the '95 front strut tops that I have but I may do a bit of experimenting to see how much more caster I can end up with them.Could be interesting.
 
 

Cheers thanks for that! Always good to know the specifics :)

You probably know that you can also dramatically increase front caster by simply reversing the top mounts front to rear.
I have never tried it but I suspect it may give a bit too much.

Reversing the top mount? You mean reverse the direction of installation? Hmm sounds interesting maybe I'll guys my suspension guys about it see what they think

With the '90 model front strut tops if you rotate them 180 degrees, the top of the strut will be moved rearwards increasing the caster.
Some people put them in that way by mistake lol.  
 
 
 

just on this, does anyone know where to get replacement early model strut tops or even have the part numbers handy??
Mine are making a fair bit of rattling/clunks now after taking it on dirt roads :(
 
Cheers
