As I understood it from an earlier post titled "motor mount hell" (IIRC) as well as the Mustangs Unlimited website, there is some difference between the convertible and hardtop motor mounts for late '65 through '68. The fan on my convertible '67 has slapped the shroud for years after I pulled the engine, but I had first thought it was just that the shroud had cracked and deformed in storage. I used some coat hanger to pull the top of the shroud away from the fan blade -- has worked fine for moving the car around the garage. Still I'd like to fix it.
Here's what I don't understand: The MU site says the correct mount for these convertibles is the "tall" mount, but if that is the case, then why is my fan hitting the shroud at the top? I would think that the wrong/"short" mount might make it hit at bottom. I suppose it could be a matter of pitch, where the taller mount would pull the top a bit back with plenty of clearance at the bottom. It could also be that my problem is indeed the shroud.
cmb68d, what body style is yours?
