I agree with Gordie, if that helps. If you're not planning on taking it on long drives on the freeway, it would be fun car. I don't think it's possible to revive an Allstate to true authenticity any more and some parts are just not available so they must be preserved by whatever means are available. This one appears to be nicely done within those boundaries.
fly out and drive it home and save $1,000. You can add overdrive when you get it home.
If it makes it home. A four without OD must be driven very cautiously. I had mine up to 65 mph... for a few minutes before it blew. My dad bought a '52 Corsair in Louisville in 1956, it was a four without OD and it had the 47/11 rear end which was supposed to be an improvement, and it still threw two rods (two separate episodes) between Kentucky and South Dakota.
I think it's a car worth preserving if that means anything.
