Found a 8 3/4,but have a question

I havent gone to look at it yet,but youre right,maybe it is a 8.25.He said he needs to keep it on the car until hes done parting it to keep it mobile so it will be weeks even before I can pull it .Are these pretty strong ?(8.25)I would love to hold off for a A body 8.75 ,but its impossible(and expensive,lol)
