IIRC, the pre NBS trucks (1988-1998) the Silverado and Sierra differences were VERY minimal. The grill should swap out 1:1.

Now, for another point, are you going to change other GMC emblems to Chevrolet?

Very funny @Pikey, I never said I was anti-GMC, I simply made a point of saying that Sierras and Silverados are virtually identical aside from cosmetics. One is not built better than the other and one is not prestigious than the other. I still find people today that think that GMC is a completely different breed of truck than a Chevrolet.
