Alright... understandable. lol, 6'1", and I can grab tools from the opposite side of the truck, but when I have to work under the dash, things get a little tight.
To each his own, right?
On stupid bolts that refuse to come out: try tightening it just a little, like maybe 1/32 of a turn. Sometimes it breaks the threads loose. lol, an impact driver usually works quite well too.
A little about water pumps: Duralast= bad, NAPA= good. The Duralast one has a sheetmetal impeller, while the NAPA one is cast iron. I learned this one after the 4th time I pulled the whole shebang apart... lol, got it down to under an hour though!
