V6 Crossmember and Perches

I am looking for the differences between V6 and V8 motor mount perches. Do they bolt in the same holes as the V8 perches? How much difference is there in the perches themselves? Pictures?

Just FYI, no I am not trying to go V6 to V8, but the other way around:newidea:

I believe the perches are the same, mounts will be different for sure. Location, I am not positive, but it seems different on all. I know on I6 to V8 they are different so it would not surprise me if the V6 is different either.

The perches are different, I sold a set quite a few years back to someone that was pulling a Chivy engine and replace it with the V6:thumbsup:

Thanks for clarifying. After looking at some photos they are different for sure.
