AC Cobra MKIV motor mounts needed
Anyone know what kind of motor mounts or part #'s for a 1986 AC MKIV?
Perhaps a 1986 Mustang GT with the 5.0 H.O.? Thank you. |
Yes,
They are the Mustang units. Rick |
Found them. Thanks, Rick!

There is a difference between coupe and convertable engine mounts. The convertables are better and I would recommend using those.
|
You're right, Gordon. It looks as though the AC guys may have used coupe mounts, unless they were changed by the original owner before I purchased the car. The convertible mounts look way different and appear to not fit. The replacements I bought fit well.
Thanks for your help. You're knowledge is comforting. :3DSMILE: Bill |
Both the coupe and convert mounts will bolt into the same place. The vert mounts tend to be about 1/4" lower. There is much less engine movement from a vert mounts.
|
Hi Gordon.
Got both motor mounts to compare. The convert mounts have a "tab" on the back to the frame which may have to be shaved to fit. Hard to tell until I'm ready to drop the engine in. I hope there will be no problem with the oil pan (Canton drag race stock looking pan) clearance with the engine 1/4 inch lower. I'll try the vert ones first. |
motor mounts
use the coupe mounts not the convt. thats how they were engineered.
|
There are aftermarket mount with Polyurethane instead of rubber, but what JBo said was right, the convert mounts are different as Ford needed to control NVH more on a ragtop. Even on the early (60s) Mustang converts, the engine mounts were different.
Understand that Brian did things based upon input from Ford and with the "flexi-flyer" AC frame, you don't want to tie the engine down too much as the loads will be fed into parts that were not intended to take such stresses......... |
Thanks, guys. I'll use what came on there originally, new coupe mounts.
