I think you should drive it and enjoy it with a good block. If you sell it one day put the block in the trunk/crate with any other part that goes with it and let the next guy think about it and spend to attempt to make it a running Matching numbers or not. Does it have to live between the inner fenders to be or not to be a matching numbers sale? Makes me think of the guy who has a fast toy option and takes off the A/C parts to have fun on the track at times and he sells the car with the complete missing parts in a box. At times one even has to fix/restore pieces if said new owner wish's it back for hopefully B&J cool aid prices. Drive it and get lots of smiles per mile's and let us other people enjoy seeing it on the road and bring back maybe a memory. I almost bought one just like it and even the same color in blue but it was hit and bent in the front a bit and so i picked the 67 front disc brake RS SS 396 4 speed and a 12 bolt beside it instead. Thank you for my memory time and one opinion on the subject at hand.
