I thought about doing this many times Id love to see a RWD LS 6 speed GP. But thats a ton of work and expect it to take years to do and not to mention how much it would cost and how many hours of labor it would take to do. If I wasnt into Mustangs as much as I am now Id consider it, I think I could get it done with help from my buddy's and guys at work but I have to many projects already. If there was someone going for this I wouldn't tell them its a bad idea because if your motivated enough and have the skills it can be done. I like the looks of a GP the only thing I dont like is it being FWD and automatic as Im sure many of you agree. Also if you get it done it would be nice to say you built your own car and after you get it done you would know everything about it. Over all Id say its worth it, if you dont have something better you would wanna build.
