Hopeful that someone has attempted this type of trim swap and knows the interchangeability of the different bumper fascias that will work.

Currently have the LT/LT3 w/3.9L Dual Exhaust rear bumper (WK option) this is the one with the double-humps for the dual exhaust, not the straight across LT trim option.
GM Part# - Description
====================
89025786 - Fascia

Want to swap in the SS trim package...rear bumper (WL option)
GM Part# - Description
====================
89025787 - Fascia
89025790 - Fascia Face
15254795 - Fascia Insert

Will the Fascia Face and Insert fit on the WK option bumper with minor modifications, or is the WL version completely different, and more than just additional holes for mounting the Fascia Face?

Thanks!

 

not sure it is what i am looking into as well i have been wondering about that as well because i am getting ready for a second muffler as well and have my monte look good with the duals with the dual hump on the bumper
