I believe I stumbled upon a '68 or '69 Belvedere...

Hello All. This is my first time here, and Guessing by my Username, you'll know i'm a Chevy guy. Truth be told, I am just a fan of the Classics, regardless of brand, make or model.

I come to you today with a question...:
I stumbled upon what I believe to be a '68 or '69 Belvedere (Coronet?), behind an old barn that collapsed. The shell looks to have been there for a while, and has had the diff, motor and trans, and column removed either before it was parked or sometime during its slumber.

Not quite sure of its original color yet, that is part of why I stopped in, or of its desirability. The car still has its bench seat and rear seat, and sweeping instrument cluster. Fenders, hood and passenger door are also missing. Firewall and front subframe seem to be in really decent shape.

I was able to get the trim tag, but not the VIN numbers, and was wondering if someone may be able to give me some info on the RPOs on the tag...?

Any help would be great. One never knows if this could end up being my newest project...

Trim tag is as follows:
20139 228095 9A227130
925 593 603

1T 6W
F5 F5 H2T T7 (sideways O)
RM23 E63 D21 214 B40645

Thanks Fellas. Any help on this would be great. :D
Lorne.
