Just for reference, Mark and myself both used the SVT shaft with the 65mm TB.



Not saying it isn't posible but it is borderline. The shaft o-ring seals are right on the edge of the TB opening and the tab for the TPS just barely sticks out past the housing...barely making contact with the TPS. I'll post more pic's tomorrow with both shafts installed in a Mustang 65mm TB to better show the differences I have described.



Some more pic's showing the differences between the shafts installed...

SVT 60mm TB on top Mustang 65mm TB on bottom...notice the TPS tab sticking out on the left on both. Also they are aligned with each other (4 TB mounting holes) to show the difference in the linkage plates/springs as well.



Distance between the linkage plate and the housing on the SVT TB (1.2455")



Distance between the linkage plate and the housing on the Mustang TB (0.8325") a difference of 0.413"



Mustang 65mm with SVT 60mm TB shaft, spring and linkage plate installed. Notice no TPS tab sticking out on the left. However no linkage clearance issues on the right.



no TPS tab...SVT 60mm is shaft too short on this end.



Mustang 65mm with Mustang 65mm TB shaft and spring(SVT spring is too big), SVT 60mm linkage plate installed. Notice TPS tab is sticking out on the left. However there is linkage clearance issues on the right.



TPS tab is where it should be to work correctly when using the Mustang 65mm TB shaft.



The tab on the SVT linkage plate needs to be trimmed down to clear the TB housing. Some trimming of the TB housing on the bottom tab to the right of the adjustment screw needs to be done as well.



If the 65mm shaft is extended to the proper length on the linkage side as Tom mentioned everything should line up and work the same as the stock 60mm SVT TB.

Hope this helps clear up some of the questions when doing this upgrade
