Question:

I currently have A Curt Q20 with base legs. Can I use my current Q20 base legs for a Curt A20 head? It looks like the bolt holes line up.

Hey Brian, thanks for reaching out!

Curt makes specific legs for the A20 # C16906 and the Q20 # C16904 so you'll need to use the correct legs for your A20 as part # C16906 in order for them to fit your application.

Hey Brian, how did things go after switching to the correct Curt A20 base legs? Knowing how the fit turned out could help others trying to match their hitch parts.
