I have the title and do know that it is a 57. It has the straight six (270 I believe). I think it is a 370 model from some pictures and some google searching......any help is appreciated! Fingers crossed my photobucket link works!

A GMC of that size should have a placard inside the glovebox door with size, engine, transmission, axle, etc. | | | | | Joined: Mar 2017 Posts: 4 New Guy | | New Guy Joined: Mar 2017 Posts: 4 | I will look in the glove box tomorrow (it's located at my office in town).
It is missing the front grill badge/emblem, and I have located a couple, I just want to get it right.
Thanks for the comments! | | |
