Try afcoracing.com as a source for parts. They have good prices and have just about everything you'll need to do this. Coil overs, links, rod ends. pre cut frame brackets, etc. They even sell the "johnny joints" used to make frt control arms. Might be cheaper than alot of 4x4 shops.(I wouldn't be supprised if this is one of they're suppliers). Great idea but will require a lot of thought to get it to handle right-hope your good at geometry!! Good luck and hope this is helpful!!
