1970 C50 vs 1970 C20???

[65standard]

I found a 1970 C50 in the junkyard. I was wondering if the dash harness would work on my 1970 C20 since they both have the same cluster. My harness is all cut up and missing connectors.

I can see there are different firewalls between the C50 and C20, but the dash looks the same. One weird thing I notice is the truck has a factory push button radio listed and the antenna, but has a factory delete plate. I'm guessing since the firewall is recessed so far back that there isn't room for the radio in the normal place?

I pulled the delete plate but I'm thinking of pulling the dash harness in hopes I can use it.
