I was looking at doing some suspension on my 67 stang. What do you guys think about the MUSTANG II SUSPENSION PACKAGE AND CROSSMEMBER ASSEMBLY from Heidt's? and what do you guys think about the original CTM Engineering T-5 IRS? This irs is bolt on and from what I've read it was the original suspension that was suppost be in the Gt350's. Having not driven any stang that's had the suspension updated I have nothing to compare the above to. Also I've priced out the M-ll suspension installation and it's between $1000-$1500 dollars. But I don't know if I can over the fact that the frame rails have to hacked up and the shock towers have to be removed. Actually removing the shock towers is pretty nice. Gives ya alot more room for MORE MOTOR! HEHE!
I saw a stang at the SEMA show with M-ll front end in it and it looked great! He had the 2" drop spindles on it which made the stance sweet!

 

I don't know much about the mustand 2 front end, but I saw a guy put in a camaro front end.
