My friend made a curved 3/4 ratchet...for the tight spots.

not really, he bent it setting the preload on a Ford 4X4 pinion. Ratchet head is still tight! He used a floor jack on a 4' cheater pipe to apply like 800 ft/lbs to the nut. Yeah, that's HF Pittsburg brand. HF wouldnt take return...! "It wasnt used as designed" Ha ha!
LOL... When I was a kid before the days of harbor freight I bought some cheap wrenches from Wal-mart cause I didn't have the money for anything better and I bent a 3/4" wrench just like that trying to get a flexplate off a 383. I kept it in my toolbox for yrs cause it was useful in tight spaces, as long as the bolt wasn't too tight.
