1973-1987 Chevy GMC Squarebody Cupholder.
Just remove your ashtray insert and this fits right in. Can be easily removed with no modification. Made out of 1/8” steel, so it is sturdy!
Will not work with manual transmission on the floor.
Ships in bare steel but can be powdercoated any color for $10 extra.
Other options available such as stainless inserts at a higher cost. I also have 64-66 and 67-72 C10 cupholders as well.
