fuel sending unit ohms question

[Cotton12v]

Iam still gathering information and getting the cummins rebuilt for my cab swap 66 c30 to a 91 dodge dually frame project. From the information i have gathered. The chevy fuel system uses 0-30 ohms and the one on the dodge uses 10 ohms full 73 ohms empty. Any advice would be greatly appreciated. I want to keep the cluster factory appearing. The dodge tank has a low fuel light I can use, but would really like the gauge to work.
