C-clip elim. are basically a bolt in deal. You will need to press a bearing on the axle. If going to the Ford ends you will have to cut the stock ends off and weld the Fords on. You'll need a jig to get them straight. You will need to get some axles that will fit the ford type bearings. Also you will either have to use the Ford brakes or an aftermarket brake to fit the ends. In the short c-clips are cheaper but sometimes leak, the fords cost more but don't leak and have a better bearing.
