Does anyone know if you can make the black plastic fender flares for the rav 4 will fit 2nd gen. 4runners?

 

You can make any thing fix with the right tools

 

If you want some nice looking flares, I'd go with what fits.
That would be the Bushwacker "Extend a Fender" fender flares.
I have install tips for the Bushwacker's on my website in the mods section.

I have the part #'s there as well.
I run also the smooth ones. I like them better than the textured ones.
I also have those part #s as well.

I bought mine at Central 4WD.
Mine as explained on my website are the smooth finish '89 to '95 truck ones for the front, and the rears are 4Runner specific only smooth ones.
They don't list them on the sight, you have to call.

The textured ones come in a complete set of 4 for the Runner.

You can also get them from Performance Products.

The flares are one of my favorite mods next to the Downey HD coils back aft.

Dirty flares

Clean flares

 

I ran across this page.

These flares look to be a bit larger (for cutout fenders?) Don't know the material, but I'll try to get more info. Shipping might be a bit much - from ICELAND!
