Pinion flange for Pumpkin swap help.

[Dark Pony]

I wanted 3.73 gears for my '15 GT with MT82 and recently purchased a whole pumpkin from a GT350. A brief search showed that they are compatible, however after doing some more reading, it looks like the pinion flange is different. Am I correct that this is what I'm going to need? It looks like the Autos and the gt350 took the same flange. Anything else that I should be aware of? Thanks for any input.

No,
You will have the 113mm flange on your 2015 manual. The picture you provided is the 110mm,
Which is what comes on all GT350’s, and 2015-2017 Automatic’s
The 113mm flange is what you need to fit your driveshaft.
