all you need is a piece of cold rolled steel maybe 3" wide, and get a machine shop to drill a hole in the middle of it so you can fit a socket onto the crank bolt. and then drill 2 holes in it to fit the 2 bolts viewable in your picture in the original post. and then you just rest it against the ground while turning the crank bolt.
nanaimo sheet metal can get you a piece of scrap metal for the bar
cant remember the name but the machine shop on wellington rd right past the chrysler/hyundai dealerships, they wil drill the shit out for you.
last time i got scrap metal that i needed for a big cheater bar, they gave it to me for free, and the machine shop will drill your stuff for $10-20
so your lookin at a cheap solution here
here lemme raw it in mspaint so theres 0% confusion
