I wouldn't have if you hadn't asked! Just trying to help especially as that one gets me sometimes too.

I was picturing something much larger than that, maybe an inch if not more in diameter! Was it really so small?

I noticed the missing heat shield too and as far as I know, they all had it.

It's the one with the longer neck that I'm trying to identify. The one with the stubby neck is from a 1951 Henney-Packard and I once had a 1948 Henney but never pulled its tank although I did get some parts from an identical one at a local vintage car parts house. I don't recall getting the tank, though, and I never had a 1946 or 1947 so I'm beginning to think that maybe the tank was inside one of my cars when I bought it!

Anyone? I'm thinking it might be a 1948 and maybe a Henney but I need some confirmation.

That all looks really good, Kevin! If you are looking for originality in final appearance, I seem to recall that the rear wheel wells have some large diameter rope-like material at the seam where they meet the fenders. You've sealed so well that it probably isn't actually needed for functionality but it will look original with it.

This, of course, is probably a last step once the mat or carpet is installed and will make the seam look nice and tidy. I'm not sure where one buys the rope, though, as I've never gotten far enough on any of my cars to need it.

As Howard (HH56) suggested, the mechanical items are not the same but it is the same system so the conversion would be identical and have the same requirements for any model. You would need to be sure you had senior parts.

There are several in the Classified Ads of my Packard / IMPERIAL page but they are the 1951-1952 type. Not sure how they different to 1953!

I converted my 1940 110 to overdrive which I can't image is much different in the basic concept to a senior model.

It required, of course, finding, rebuilding and installing the overdrive transmission and its added supports, cable, wiring, relays, kick-down switch and all the obvious stuff but it also meant shortening the drive shaft and replacing the rear end with the proper ratio for use with overdrive. This latter isn't absolutely necessary but it will make adding it a bit better for highway driving as the non-overdrive rear end was something of a compromise for keeping the RPMs somewhat reasonable at speed but sacrificed the power from a stop. On a junior it made a big difference but maybe not so much on a senior!

This was at least forty-five years ago and cost several thousand dollars but would cost far, far more now especially due to the fact that parts that were difficult to find then will be much harder to locate now!
