Could be worth a look. I can’t tell if this had bench seats in the back or not.

“1961 Willy’s Wagon body with clean Oregon title sitting on a late 80’s S15 Chevy Blazer frame. Original bare Willy’s frame included. No motor or trans installed but includes a rebuilt, low mileage Chevy 4.0 motor. WIlly’s is a rare barn door style panel van body but a previous owner cut side windows into rear panel area. Clean, straight, solid, 99% rust free body. This is a “project vehicle” ready for restoration. Delivery near or far available for a reasonable fee depending on distance”
