See if you can find one for a Thunderbird turbo coupe, it's the same engine and should be tuned for the same frequency vibrations.

Mustang Svo Parts

84,85,86 SVO...83,84,85 Turbo GT....83-88 Thunderbird 4 cyl Turbo...

if you get in a bind, try one from a standard Mustang 4..

You can find it on good car parts and accessories stores or shops either here in the net or in your local area. Try to search it first, then you can be able to determine the good part that you may have for your stang.

People often forget that the merkur xrt4i also had the same engine...granted it's a flaming p.o.s. but same engine at least. Otherwise go to a ford dealership with the part number (if you can find it).
