Strut tops interchangeable?

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?

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.

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.
 
 

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.

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.  
 
 
 

Prices quotes from Amayama

• 48609-17030 – Front early $100.
• 48750-17020 - Rear early $142
• 48609-17040 – Front late $114.
• 48750-17040  – Rear late $96 

Cheaper to go Front early and late rear hehe
 

For early models Lithia quote $89 USD +ship.
I have wondered if the old bearing could be pressed out and a new one fitted.
Could be cheaper.
BTW, I found early and late rear top mounts are interchangeable.
The difference is in the mounting stud length.
 

My quotes don't include postage sorry :/
Nice one Red I'm gonna do the same to mine once I get zem in :)
Do you feel any changes on handling?
