How can I convert to factory dash gauges?

[1972BlueC20]

Ok I'm about to buy the full cluster gauge and make the switch from idiot lights to a full gauge cluster.

I'm buying the new complete cluster, the copper oil line, a tach filter and I got and new sending unit for the coolant temp.

Here is the stuff I bought for the wiring. The red wire is for the new line to the alternator. The black is for the new line to the junction block. Both will have an inline 4A glass fuse.

Will all this be sufficient to do the work? I've done some wiring before, but I'm not a pro. Please let me know if I need to take anything back and swap for something else or something better.
