Few little issues need some guidance on.

So ive finally pieced my 74 Duster 318/904 together from a box and car full of parts. I have it to where its running and driving now. But now for my issues:

Takes a while to start turns over fine and will finally kick over and start about 6 or so tries.

Transmission is leaking out of the bellhousing while its sitting

Leaking coolant from the small J hose from the water pump (Clamp is off just a enough to leak under pressure easy fix)

Oil Pressure Dummy light flickers every once in a while.

After car is hot nt to start very easily and seems like its binding before it will finally start after a couple of pumps of the gas pedal. (2bb carb)

Transmission doesnt want to shift until o let off of gas when driving. (Kick down needs adjusted?)

Reverse lights dont work all the time but will come on every once in a while

Brake lights dont work at all but tail lights do

Keeps blowing the #7 20A fuse for some reason.

Horn constantly stays on even with switch disconnected.

That is all the issues i have seen so far and im working on making this my daily driver for around base due to my Hellcat drinking gas faster than a dual quad at wide open haha. Any one have any ideas about what could be the causes for any of these that i have no already found by looking for the leaks?
