Trying to identify correct 32 truck gauges

[32B]

My 32 model B truck came with an empty dash. I was able to get my hands on several 90mph speedos that I was told were for a 32 B truck, but im just not sure. Was the speedo any different in the big trucks than the pickups? I once saw on here a speedo that had different colors and speeds by gear and I thought it said it was for a 32 big truck, but I can't remember. Either way, just trying to figure out the correct gauges and then finding what is necessary. I can post pics of what I have 2night if it would be helpful. -Thanks
