five lug conversion

some pb blaster and alot of scraped knuckles. Seriously, this is a time consuming swap and one that I would think really hard on what you want out of it. Are you just wanting 5 lug wheels? Are you shooting to kiss the windshield when you stop? As pointed out above there are a few different options.
 
This can be done pretty cheap these days. Worth it if you've got the time. Find a junked 94-95 v6 mustang and rip it apart. Spindles, axle shafts, etc. Same parts as the V8 cars, v6 car parts will usually be cheaper, it was for me. Another cheap upgrade is to grab the front calipers off a 99-04 Mustang. They are PBR dual piston. Lots of information on here us google and the search function
