Finding tuning fender kits is next to impossible for older rwd Toyotas. Handy hobbyist doesn't let this matter stop him - he will install a kit from another brand.
This will work on any old Toyota of course, despite sample photos being model biased.
Here is an example of stone age Ford Escort Mk I fenders bolted onto KP-series Starlet.
I've heard VW Golf Mk I fenders are used on Starlets as well, they could be these - sorry, I'm not absolutely positive.
