This trailer is a 1993 and the coupler is an a frame that is welded to the angle iron beneath it. I was wagching a how to video earlier this afternoon and i saw a part about extended shanks for certain couplers and i thoight maybe i had this oddball coupler. Nope. I looked for adjustments and found none. However after getting a flashlight and inspecting the inside of the coupler housing I found a little flange that was keeping the other component from doing its job. I thank you guys for your quick response you’ve saved me time and more headache.
