ys it will Y@KSVT has it in his car right now...don't you?
no...it will not work correctly, the tab does not stick thru far enough to properly connect to the TPS. Also the o-rings/groves just barely catch the edge of the bearings that may lead to a possible leak. You need to use the SVT linkage plate on the 65mm TB shaft for it to work correctly.
no I don't have one on my car right now 
Here are accurate measurments of the SE 54mm, SVT 60mm, & Mustang 65mm TB shafts.
SE 54mm: 5.368" (5.865" end-to-end, tabs included)
SVT 60mm: 5.368" (5.760" end-to-end, tabs included)
Mustang 65mm: 5.192" (5.584" end-to-end tabs included)
They are not interchangable do to the spacing of the o-rings/groves on either side of the plate and the offset of the plates as well.
Here are some pic's of the TB shafts w/end linkage plate and TB plates. In the same order as they are listed above.
SVT 60mm TB shaft (black one) & Mustang 65mm shaft...Mustang TB shaft is a good bit shorter then the SVT TB shaft.
With the TB plate slots lined up you can see how the SVT TB shaft (top) will be too short on the TPS side and too long on the linkage side.
SVT 60mm TB shaft (top) & Mustang 65mm TB shaft (bot) with linkage plates removed

now it will work in the Mustang 65mm TB with some monor mods to the Mustang TB housing around the spring retainer tabs.
