NOBODY! Seriously, before I sold all of my '69 cars and parts I was going to install an IFS kit I saw in Car Craft magazine. Nice kit, forgot the name. Anyway, the kit was a little spendy so I started asking around about a MustangII front end, and everyone told me to send the entire friggin car to California.
If you are serious about this, find that IFS kit. It's a complete kit, and a true bolt-in.
I ordered and am going to be putting in a Rod and Custom Motorsports IFS...its the rc-107 with adjustable coil-overs, 11" disc brakes, power steering, 2" drop spindles, etc. should be pretty sweet when its done. Its the same frontend as that in the 66 mustang gt350h in the last Popular Hot Rodding magazine. More later...
