A 1973 GMC Sierra Grande 454 for the archives
 

Hey Folks

I have posted in the 67-72 realm because I have a 1970 GMC Sierra Grande, but I discovered this 1973 model. It's very original, very well-optioned and only 108,000 miles. I took some pics as well...enjoy, HenryJ



(*1) I wasn't aware that there was an animal associated with the Sierrra Grande! Unable to determine if it's a Bison/Buffalo or Steer....

(*2) Also does anyone know what option Z88 GMC conversion means?

I'd love to have that truck and use the body to replace my rusty one.

1. It looks like a bison. Not sure of the connection, but my '74 Custom Deluxe has a cowboy hat. Not something I would normally associate with it, but what so I know.

2. I think Z88 is just the option code for the Sierra Grande package. It sounds right, anyhow.

Z88 is the option that drives all the GMC emblems.

These days there is also a comparable RPO for Cadillac = Z75.

And there is also an RPO for Chevy = X88.
