Good amount of parts out there, just have to get the right ones. If it is a true 57 CJ5, it will have the inline 4 cyl, which is bullet-proof...it is gonna ride like an old Willys, since it has no power steering (should be the old ross type, not saginaw), no power brakes (all manual hydraulic drums), and noisy...but those are all fun parts of owning an early CJ5. Just be informed that the "newer" CJ5 parts are not really gonna work. There is a lot of 1976 and up CJ5 parts, but very, very little will work for you from the "late" model CJ5. Most stuff from 1970 and older should work on that model. Post some pics so we can drool...I love the old 5's and CJ3B's.
