Re: 1979 k5 using parts from a 1986 k5

You are changing pretty much the whole drive train so it should be fine but you will need drive shaft, shift indicator, trans cross mount and mounting bushing, then you have to see about e-brake system you would like to set up.( the bracket for the 84-87 cables). As for the Cluster if it has the same option as your it easier.
You will have to check the wiring plug for a few changes between 79 and 86. if the 79 did not come with gauges and the 86 did then there a lot more repining. If you look up cluster threads more info on this here.
