Having a heck of a time finding rear seat covers for a 50/50 split 1st gen 4runner. I figured the 2nd gen covers could probably fit with some work but to my surprise there are very few options for a 2nd gen rear seat cover either.

Had a lead on rear covers for a 2nd gen on ebay but after purchasing seller said they no longer had the covers and refunded me. .
I was able to find a couple of more custom seat cover places that claim they do 2nd gen covers but they are too expensive. I was looking for a cheap -$150 more universal type set. Also found some Toyota new OEM 2nd gen rear covers but $275 each and total over $500 for the whole back seat

 

i got these from rockauto, very nice for the price, lots of options:
