Been wondering the same thing for my 88 GL. Seems like all the parts are for newer subaru's. I know older toyota parts are even somewhat easy to find. Hopefully someone will point you in the right direction and I can piggy back...
Get it! I just bought one but an 88 very clean auto with 103000 miles. Paid 700. Only issues is I have to replace the drivers side turn signal lens to pass safety inspection...lol. And that's the original paint!
