If you go with with James Duffs extended radius arms, and track bar mount, EB/RBV coil buckets, its a pretty much bolt on affair. But thats all big money....
Otherwise you will need to buy either a premade trac-bar mount and fab it to work for you, or fab your own trac bar bracket.
Also, you will need to fab a tranny mount and possibly either mod the current buckets to take EB coils, or buy some generic ones (but will still require a minimum of fab possibly).
Its not hard if you know how to use a torch, grinder and of course you know how to weld good. If you don't, it'd be a pretty duanting, time consuming SOB.
Course, if you have buddies that will do the above for some
then you are all set to go once to gather the majority of the parts.
Also, this is not a over the weekend project (for some it is, but for most it is nto). If you know what you are doing count on 1-4 weekends or 2 weeks solid(ish, all persons take a different amount of time). The most time consuming part, is the research involved to figure what to buy, and what to do with what you buy.... If you have never done this thing before, get another DD, and park the project rig for an extended period of time. Crap always creeps up, and the proccess will always taking longer than expected...
