Well, I've tried to to stay silent in all this. Reading all these post is giving me a headache. I'm not sure how many of these MII are out there, but I for one, have installed several. I'm also planning on installing more. I have had 0 failures. I've had 0 Complaints. I've had 0 problems of any kind. I have cut out several cracked, broken, twisted, rusted, totally failed Shock towers. What will the MII do after 40 yrs? Probable the same, Would I road race my 67 Fastback with MII? NO WAY. Would I road race your 67 Fastback with a MII? I would drive it like I stole it. Now Then, If anyone is fool enough to chance their car in that way, the suspension under the front won't make much difference. Let's face it, most of these cars are beautiful restored classics. The majority of owners drive them with some care. The owners that don't, should care about twist, fatigue, failures, It's going to happen. I agree with Reen, If your restoring a Mustang, and your going to take care of it when your done, a MII is a great option to get all the neat things you want in one package,(Disc brake,Rack,Ect). It is very simple to install. However, If you can't weld, It's a problem. But really, if you can't weld, a restore on most Mustangs is a problem. If you like a 40 yr old suspension that is tried & true, then the original setup is best for you. Of course, I wouldn't change to Disc front brakes either, Those old Drums are tried & true too!!! Just my 2 cents worth, I don't really have any degree, I've just been restoring these old Rust buckets for 21 years now. WWW.Mustangmaker.com Thanks.
