Yea, my 87' has screw in ball joints. It made rebuilding the A-Arms simple. BUT there are no extended swing arms made for the older Warriors only this
Here's a pic of the replaceable ball joints that I bought for $90 off Ebay. they are not easy to get out but heat works well.
I rebuilt my entire quad except for the motor.
When i bought mine it was sold to me as a 95'. I didn't know any better. I soon found out it was a 87' and just as stated before there is not a lot of interchangable parts on the A-Arms, and swingarms.
So far i have rebuilt all bushings and ball joints on the front a-Arms, repainted the frame, rebuilt the rear end with a new aluminum carrier by R.A.D., new Dura Bluwe axle and all new bearings.
New front Calipers because it was missing one and the other had been used so long without a brake pad it had ate through the caliper.
On mine the front end components are all 87' because I tried 01' front a-arms and calipers and those didn't fit, that was a live and learn moment.
The plastic is the blue plastic from a 01' which fit on perfectly. I am not running a headlight at this time because my 87' headlight didn't work with the 01'plastic but I plan to get some new fog lights to fit to the new plastic for trail riding.
The rear aluminum carrier is made for 90' and up but still fits just fine, just had to make some spacers for the rear cailper to fit on with longer bolts.
The rear sprocket hub on the 87's is a 4 bolt hub and the newer ones are a 6 bolt configuration I think.
My warrior came with Beadlocks on it from a Suzuki LT500 Quadzilla with 5 lugs wheels and hubs. I like that, I thought it was cool to have the 5 lug wheels and hubs, but it does make it a little difficult if I was to need to change wheels a lot, like in a racing situtation but I only trail ride.
That is something people may not know is that the Suzuki hubs fit the Warrior axles as well.
Another little mod I did was, after my exhaust Manifold bolts snapped and then I snapped the EZout in the broken off bolts in the head I decided to mount it like the Suzuki Quadzilla did, I used Springs to tension mount the exhaust pipe to the head. It makes it really easy to put on and take off and it works perfectly. Just had to make some L brackets on the exhaust pipe to connect the springs to. It's a nice mod.
I did just recently add a 2000 model Carb to it and realized the throttle cable is different than the 87's. I have a new throttle cable coming in the mail.
Here is what it looks like now from red plastic and red frame to black frame blue plastic
