I have a 1955 cj5 and a friend has a 1969 scout 800, he took the stock axles off his scout and I would like to get them if they would be an improvement, are they split axles or solid how wide are they in ralation to my stock jeep?

I have already got a complete new brake system from backing plates out and need to know if they will fit on the scout axles. I would appreciate any help I could get.

thanks
