Default Bung Size btwn 09 & 10 FXDF?

Probably going to Thundermax w/ Auto Tune on my 2010 FXDF. Heard there is a difference in O2 sensor bung size - smaller on the 2010 (smaller O2 Sensors) than on the 2009 (larger O2 bungs). The TMax uses the larger size. Trying to avoid an "Oh Crap" moment once I get her torn apart. Anyone know of there is a difference?

I have a 2010 FLHX street glide. just put a pair of Vance and Hines dresser dual headers on. I'm using a PC-V and had to plug the o2 bungs. I went to the hardware store and bought two - size 12x1.25mm bolts and washers - works great and spent about $8. I would double check and see if the T-max had a set up for the 2010. In other words the size for my 2010 was 12mm. hope this helps
