Do Demco A-Frame Trailer Coupler DM14793-81 and Demco Cast Head Coupler DM37ZR Use Same Hole Pattern

Question:

I have this item part # DM37ZR already installed my trailer tongue and fits perfect with the bolts as I drilled the holes exact on the frame but now I want to change it for this coupler # DM14793-81. Will the bolt configuration I drilled out work seamlessly for installing this part # DM14793-81 as a direct replacement onto my frame. I’m worried that the bolts will not align through the coupler and the frame because maybe there is variation in the hole placement on the a-frame base of the coupler between the two. The reason why am looking to change it is to gain extra length on the front end of the coupler. Thanks!

The Demco A-Frame Trailer Coupler part # DM14793-81 and Demco Cast Head Coupler part # DM37ZR both install using the same three hole pattern spaced 3" apart on center so you should be able to switch between them pretty easily.
