RE: WATCH OUT! Another Brain Storm...
Could be but the mount in the top photo is located in the same place as the mount on my 430 T-Bird and even looks like the same pad but you are correct. There is a difference and a reason for the difference. Could it be exhaust pipe bends due to cross member location?
Walter's tube was the same as the tube in the photo of the 430 above. Identicle right down to the spot welds on the mounting tab. The tube I bought from Mike is for a T-Bird style mounting as 430MEL says his is mounted. The other one must be for Lincolns.
