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

I lengthen the shaft with an additional piece. I actually will weld it on and the shape the new slot/tab myself to the correct angle. Then I'll tack weld the linkage lever on. If need be I make a new thottle stop.
If you host it I'll send you a comparison picture of one I did last week.
gimme an email.

Got it...I have put the shaft in a lathe and drill/tap the end and use a screw/lock washer to attach the linkage lever. Works very good but the shaft is still short as mentioned. I have the tools and ability to make completely new shafts but it is a PITA to do. The entire shaft needs to be turned down do to it being an odd diameter so starting with larger dia. S/S stock is necessary.
Sure I'll host it...sent you a PM with e-mail
Thanks,
Scott

Anybody have pictures of their T/B with this modification? This seems to be easier than extending the length of the shaft, as I'm still having a tough time picturing that.

Not really. Extending the shaft is easier because it DOESN'T require the exact same 10mm diameter shaft. You can use 3/8" shaft which is a heck of a lot easier to get because only the springs ride on it with the plastic bushing. If you don't weld it on like I do and then smooth out the welds then you could bolt it together as scott is doing.

This is based 100% off of memory, and is for an SVT application.
The 65mm T/B swap is pretty easy. Once you have it apart, and start putting it back together, you'll see what needs to be ground off.
1. Remove TPS
2. Remove 2 screws holding the plate into the shaft.
3. Remove plate from shaft.
4. Remove shaft from T/B
5. Rotate shaft 180 degrees and insert back into T/B
At this point, you'll have to rotate the shaft as if it would with the throttle cables turning it. This will tell you what needs to be ground/cut off.
6. Grind the tab on the T/B that has the stopper on it. If you are looking at the opening of the T/B, as if standing at the driver's side of the car, the tab will be at the lower right corner of the T/B. You'll need to grind that down, so the cam/spring have enough room to rotate at WOT.
7. You'll need to also cut off one of the cam tabs. I believe this cam tab is on the bottom of the cam, if looking at the opening of the T/B from the driver's side of the car. Otherwise, the shaft won't open all the way.
8. Reinstall the plate, once you know that the shaft will rotate 90 degrees(WOT) when installed onto the UIM.
9. Reinstall the screws that hold the plate into the shaft.
Just make sure you wind the spring around so there's tension. Otherwise, you might get some throttle hang.
10. Install T/B onto UIM.
11. You'll need to bend the top cam tab up a little bit, so it hits the UIM, unless you want to fab up a stopping tab so the T/B doesn't open past WOT. I just let it hit the UIM.
12. Install the SVT TPS onto the newly modded 65mm T/B.
Sorry I don't have any pictures. You can PM me if you have any questions.
