Jennifer, welcome to the forums, you'll probably get the info you are looking for here.
You won't find your VIN info online... GMC did funny things and are rather confusing. I don't understand 1/2 of them, but, we do have a couple GMC VIN guys floating around.
I CAN say, that the VIN starting off with cm10dp breaks down like this;
C = 2 wheel drive
M = V-6 gas motor (probably 305 as you indicated)
10 = GVW.. 1/2 ton
D = body type, Wide/fleet side
P = Assembly plant, Pontiac Mi.

I think that's what it breaks down to... I'm sure some one will correct me if I am wrong.
