We are looking for rear left & right bumper fillers and also the center bumper filler for this vehicle. When searching the internet, we are finding limited options. From the reviews, we are concerned that the fit of the aftermarket products do not fit very well. The second concern is the slow shipping. Has anyone had any good experiences finding these parts? Likewise, anyone had any not so good experiences and suppliers we should avoid. Please help us locate these parts. We are restoring/repainting the lower rear quarter panel on each side of the vehicle. Thank you, Carl

 

I am afraid that the reproduction parts will take some or a lot of manipulating
to get them to fit! The repop fillers are usually made of a stiffer material than the originals.

If you're concerned about the fit it's worth it to give them a call before you purchase the bumper fillers.
