If you already have all the SWP stuff then just buy a short water pump. That's what I did when I bought my GM crate engine. Had to grind down one big headed bolt and that was about it. I installed Flowkooler water pump from Summit. I tried to give away that LWP but nobody seemed to want one so after years I just tossed it.

Consider buying a Edelbrock aluminum coolant pump, if you have to get a new water pump.

Long water pump setups reverse the alternator and A/C compressor to opposite sides of the engine and do not work well with a Corvette.
Also....the Corvette pump is not just a Short unit....it also has a larger shaft (3/4" vs. 5/8").....so it is important to get the right one to mount standard Corvette fans and pulleys.
67-72 Chevrolet pickups were very similar to the Corvette FYI.
No way would I try and make a Long Water pump setup work on a C3 Vette.....even if I had the stuff.

He's having issues with the bottom radiator hose.

I would swap out the water pump and get rid of the problem. A lot of the stuff will still work.

What is your question? You have a long water pump. long water pump accessories, and elec fans. Just hook it all up. You should have more than enough room with those electric fans.
If it is just the hose then hook it up to the water pump and then see how much you have to cut at the other end to attach it to the radiator.

Post a picture if you can.
