Hey guys,
Looking for a stock file for a 2013 Silverado 5.3 I believe, Tis shows OS #12654014, I can't find one online anywhere.

Vin is 1GT120CG6DF188470

Thanks for any help!

That is an E78 OS, 6.0L too.

Good to know, I just confirmed it is a 5.3 motor. Don't know if the E78 version will work or not, any insight on that?

Thanks!

I have never seen the E78 used on a 5.3L, so I don't know what is going on with that truck.
