Same question, I measure the threads and is 5/8", I measure the splines and its like 3/4", the tapered shaft is like 7/8". What is it? The spline size? Seen them on eBay in 5/8 and 3/4" sizes. I'm thinking it has to be the spline size cause that is what you weld to?
Got a pro-armor assault steering wheel I need to mount, nice product and only 58 bucks.
